Haplogroup Q-M242

Haplogroup Q or Q-M242 is a Y-chromosome DNA haplogroup. It has one primary subclade, Haplogroup Q1 (L232/S432), which includes numerous subclades that have been sampled and identified in males among modern populations.

This article is about the human Y-DNA haplogroup. For the human mtDNA haplogroup, see Haplogroup Q (mtDNA).

Q-M242 is the predominant Y-DNA haplogroup among Native Americans and several peoples of Central Asia and Northern Siberia. It is also the predominant Y-DNA of the Akha tribe in northern Thailand and the Dayak people of Indonesia.

Origins

Haplogroup Q-M242 is one of the two branches of P1-M45 also known as K2b2a (The other is R-M207).

Q-M242 is believed to have arisen around the Altai Mountains area (or South Central Siberia),[2] approximately 17,000[2] to 31,700 years ago.[3] However, the matter remains unclear due to limited sample sizes and changing definitions of Haplogroup Q: early definitions used a combination of the SNPs M242, P36.2, and MEH2 as defining mutations.

Technical specification of mutation

The polymorphism, “M242”, is a C→T transition residing in intron 1 (IVS-866) of the DBY gene and was discovered by Mark Seielstad et. al. in 2003. [11] The technical details of M242 are:

Nucleotide change: C to T
Position (base pair): 180
Total size (base pairs): 366

Reverse 5′→ 3′: tccaatctcaattcatgcctc

Subclades

In Y chromosome phylogenetics, subclades are the branches of a haplogroup. These subclades are also defined by single-nucleotide polymorphisms (SNPs) or unique-event polymorphisms (UEPs). Haplogroup Q-M242, according to the most recent available phylogenetics has between 15 and 21 subclades. The scientific understanding of these subclades has changed rapidly. Many key SNPs and corresponding subclades were unknown to researchers at the time of publication are excluded from even recent research. This makes understanding the meaning of individual migration paths challenging.

Phylogenetic trees

There are several confirmed and proposed phylogenetic trees available for haplogroup Q-M242. The scientifically accepted one is the Y Chromosome Consortium (YCC) one published in Karafet 2008 and subsequently updated. A draft tree that shows emerging science is provided by Thomas Krahn at the Genomic Research Center in Houston, Texas. The International Society of Genetic Genealogy (ISOGG) also provides an amateur tree.

Phylogenetic variants

The subclade (under Q-MEH2) proposed by Sharma (2007), which shows polymorphism (ss4bp, rs41352448) at 72,314 position of human arylsulfatase D pseudogene, is not represented in any current trees under Q-MEH2.[16] The most plausible explanation for this could be an ancestral migration of individuals bearing Q-MEH2 to the Indian subcontinent followed by an autochthonous differentiation to Q-ss4bp.[5]

Distribution

Americas
Further information: Genetic history of indigenous peoples of the Americas and Y-DNA haplogroups in indigenous peoples of the Americas

Several branches of haplogroup Q-M242 have been predominant pre-Columbian male lineages in indigenous peoples of the Americas. Most of them are descendants of the major founding groups who migrated from Asia into the Americas by crossing the Bering Strait.[2] These small groups of founders must have included men from the Q-M346, Q-L54, Q-Z780, and Q-M3 lineages. In North America, two other Q-lineages also have been found. These are Q-P89.1 (under Q-MEH2) and Q-NWT01. They may have not been from the Beringia Crossings but instead come from later immigrants who traveled along the shoreline of Far East Asia and then the Americas using boats.

It is unclear whether the current frequency of Q-M242 lineages represents their frequency at the time of immigration or is the result of the shifts in a small founder population over time. Regardless, Q-M242 came to dominate the paternal lineages in the Americas.

North America

In the indigenous people of North America, Q-M242 is found in Na-Dené speakers at an average rate of 68%. The highest frequency is 92.3% in Navajo, followed by 78.1% in Apache,[2] 87%[2] in SC Apache,[17] and about 80% in North American Eskimo (Inuit)–Aleut populations. (Q-M3 occupies 46% among Q in North America)[18]

On the other hand, a 4000-year-old Saqqaq individual belonging to Q1a-MEH2* has been found in Greenland. Surprisingly, he turned out to be genetically more closely related to Far East Siberians such as Koryaks and Chukchi people rather than Native Americans.[19] Today, the frequency of Q runs at 53.7% (122/227: 70 Q-NWT01, 52 Q-M3) in Greenland, showing the highest in east Sermersooq at 82% and the lowest in Qeqqata at 30%.[20]

Q-M242 is estimated to occupy 3.1% of the whole US population in 2010:[21]

Ethnicity Percentage of USA population † Haplogroup Q frequency
White people 63.7% Q-P36* 0.6% & Q-M3 0.1%
Hispanic 16.3% Q-P36* 3.8% & Q-M3 7.9%
Black 12.6% Q-P36* (xM3) 0.2%
Asian 4.8% ~0%
Native American ‡ 0.9% Q-P36* 31.2% & Q-M3 26.9%

† According to the US National Population Census data (2010)[22]

‡ Mainland and Alaska, not including the Pacific islands

Mesoamerica & South America

Haplogroup Q-M242 has been found in approximately 94% of Indigenous peoples of Mesoamerica and South America.[23] Q-M242 built many ancient cultures and civilizations such as Tiwanaku, Caral(Norte Chico civilization), Maya, Inca, Aztec, and so on.

As a result of five centuries of wide-scale biological mestizaje, or miscegenation, between indigenous Americans and European immigrants, today in Mesoamerica and South America the frequencies of Q-M242 (mostly M3) among the whole male population of each country are lower than indigenous Amerincan populations, but nonetheless run far higher than in the population of North America.

The frequencies of Q among the whole male population (inclusive of all mixed-race and mono-racial groups) of each country reach as follow:

Based on the data above, the average frequency in the whole male population of Mesoamerica and South America is estimated to be about 18%.

Asia

Q-M242 originated in Asia (Altai regions), and is widely distributed across it.[2] Q-M242 is found in Russia, Siberia (Kets,[6] Selkups, Siberian Yupik people, Nivkhs, Chukchi people,[37] Yukaghirs, Tuvans,[38] Altai people,[8] Koryaks, etc.), Mongolia,[39] China,[40][41] Uyghurs,[39] Tibet,[42] Korea, Japan, Indonesia,[43] Vietnam,[44] Thailand,[45] India,[46] Pakistan,[46] Afghanistan, Iran,[47] Iraq, Saudi Arabia, Turkmenistan, Uzbekistan, and so on. (For details, see below.)

North Asia

In Siberia, the regions between Altai and Lake Baikal, which are famous for many prehistoric cultures and as the most likely birthplace of haplogroup Q, exhibit high frequencies of Q-M242. In a study (Dulik 2012),[48] Q-M242 (mostly Q-M346 including some Q-M3) has been found in 24.3% (46/189: 45 Q-M346, 1 Q-M25) of all Altaian samples. Among them, Chelkans show the highest frequency at 60.0% (15/25: all Q-M346), followed by Tubalars at 41% (11/27: 1 Q-M25, 10 Q-M346) and Altaians-Kizhi at 17% (20/120). In a former study, Q-M242 is found in 4.2% of southern Altaians and 32.0% of northern Altaians with the highest frequency of 63.6% in Kurmach-Baigol (Baygol). The frequency reaches 13.7% (20/146) in the whole samples.[8] In another study,[49] the frequency rises up to 25.8% (23/89: all Q-M346) in Altaians. Based on the results of these studies, the average frequency of Q-M242 in Altaians is about 21%.

Tuva, which is located on the east side of Altai Republic and west of Lake Baikal as well as on the north side of Mongolia, shows higher frequency of Q-M242. It is found in 14%[50]~38.0% (41/108)[49] of Tuvans. Also, Todjins (Tozhu Tuvans) in eastern Tuva shows the frequency at ≤22.2% (8/36 P(xR1)[51])~38.5% (10/26, all Q-M346(xM3)).[49] So, the average frequency of Q-M242 among Tuvans-Todjins in Tuva Republic is about 25%. Haplogroup Q-M242 has been found in 5.9% (3/51) of a sample of Tuvans from the village of Kanasi, 9.8% (5/51) of a sample of Tuvans from the village of Hemu, and 62.5% (30/48) of a sample of Tuvans from the village of Baihaba in northern Xinjiang near the international border with Altai Republic.[9]

In Siberian Tatars, the Ishtyako-Tokuz sub-group of Tobol-Irtysh group has a frequency of Q-M242 at 38%.[10]

The highest frequencies of Q-M242 in Eurasia are witnessed in Kets (central Siberia) at 93.8% (45/48) and in Selkups (north Siberia) at 66.4% (87/131).[6] Russian ethnographers believe that their ancient places were farther south, in the area of the Altai and Sayan Mountains[2] (Altai-Sayan region). Their populations are currently small in number, being just under 1,500 and 5,000 respectively. In linguistic anthropology, the Ket language is significant as it is currently the only surviving one in the Yeniseian language family which has been linked by some scholars to the Native American Na-Dené languages[52] and, more controversially, the language of the Huns. (See: L. Lieti, E. Pulleybank,[53] E. Vajda,[54] A. Vovin,[55] etc.) Q-M346 is also found at lower rates in Sojots (7.1%, Q-M346), Khakassians (6.3%, Q-M346), Kalmyks (3.4%, Q-M25, Q-M346)[49] and Khanty,[56] and so on.

In far eastern Siberia, Q-M242 is found in 35.3% of Nivkhs (Gilyaks) in the lower Amur River, and 33.3% of Chukchi people and 39.2% of Siberian Yupik people in Chukotka (Chukchi Peninsula).[37] It is found in 30.8% of Yukaghirs who live in the basin of the Kolyma River, which is located northwest of Kamchatka.[38] It is also found in 15% (Q1a* 9%, Q-M3 6%) of Koryaks in Kamchatka.[26]

East Asia

In some studies, various subgroups of Q-M242 are observed in Mongolia. Q1a2-M346 (mostly Q-L330) occupies 1.4[26]~3.1%[47] of Mongols (1/2~2/3 among Q samples), followed by Q1a1a1-M120 (0.25[26]~1.25%[47]), Q1a1b-M25 (0.25[26]~0.63%[47]), Q1b-M378. In another study, Q is found in 4% of Mongols.[23] Karafet et al. (2018) found Q-L54(xM3) in 2.7% (2/75) and Q-M25 in another 2.7% (2/75) for a total of 5.3% (4/75) haplogroup Q Y-DNA in a sample of Khalkha Mongols from Ulaanbaatar, Mongolia.[57] Based on these studies, the average frequency of Q-M242 in Mongols is estimated to be about 4~5%.

However, most of Q-M242 people in East Asia belong to subclade Q-M120, which distributes most intensively across northern China (the provinces of which the capitals locate northern to Huai River-Qin Mountains line). Q-M242 ranged from 4~8% in northwest China (Xinjiang, Gansu, Shaanxi), north China (Shanxi, Hebei), central China (Henan), and upper east China (Shandong) to 3~4% in northeast China. The average frequency of Q-M242 in northern China is around 4.5%. However, it decreases to about 2% in southern China.[40][41] In a study published in 2011, researchers have found Q-M242 in 3.3% (12/361) of the samples of unrelated Han-Chinese male volunteers at Fudan University in Shanghai with the origins from all over China, though with the majority coming from east China.[58] In another study published in 2011, Hua Zhong et al. found haplogroup Q-M242 in 3.99% (34/853, including 30/853 Q-M120, 3/853 Q-M346, and 1/853 Q-M25) of a pool of samples of Han Chinese from northern China and 1.71% (15/876, including 14/876 Q-M120 and 1/876 Q-M346) of a pool of samples of Han Chinese from southern China.[59]

Q-M242 has been found with notable frequency in some samples of Uyghurs: 15.38% (22/143, including 6/143 Q-M378, 5/143 Q-P36.2*, 4/143 Q-M120, 4/143 Q-M346, 1/143 Q-M25) of a sample of Uyghurs from the Turpan area (吐鲁番地区),[60] 7.9% (6/76, including 2/76 Q1b1-L215/Page82/S325, 1/76 Q1a2-M346*, 1/76 Q1a1a1-M120, 1/76 Q1a2a1c-L330*, 1/76 Q1a2a1c1-L332) of a sample of Dolan Uyghurs (刀郎人) from Horiqol Township of Awat County,[61] and 7.74% (37/478, including 24/478 Q-M346, 7/478 Q-P36.2*, 5/478 Q-M120) of a sample of Uyghurs from the Hotan area (和田地区).[62] However, other studies have found haplogroup Q in much smaller percentages of Uyghur samples: 3.0% (2/67) Q-P36 Uygur,[63] 1.6% (1/64) Q-M120 Lop Uyghur (罗布人).[61] Haplogroup Q was not observed in a sample of 39 Keriyan Uyghurs (克里雅人) from the village of Darya Boyi, located on the Keriya River deep in the Taklamakan Desert.[61]

Haplogroup Q was observed in 3.2% (5/156 : 2 Q-M120, 3 Q-M346) of males in Tibet in one study[42] and in 1.23% (29/2354) of males in Tibet in another study,[64] but this haplogroup was not observed in a sample of males from Tibet (n=105) in a third study.[63]

It is found in about 1.9% of South Koreans,[65][66][67] showing the highest frequency in Seoul and Gyeonggi Province at 2.7% and decreasing ones to the south (Kim 2010). It has been found in about 0.3% of Japanese[68][63][69][70][71] (with known examples from Shizuoka[63] and Saitama[70]) and in 0.3%[45]~1.2%[72] of Taiwanese.

Subclade Q1b-M378 is also found in China and its neighboring countries at very low frequencies. It exists throughout all Mongolia, with rare examples in Japan.[73]

Southeast Asia

Haplogroup Q shows low frequencies in Southeast Asia. In a study,[43] the frequencies of haplogroup Q is 5.4% (2/37) in Indonesia, 3.1% (2/64) in the Philippines, 2.5% (1/40) in Thailand. However, other studies show 0% or near 0% frequencies in those countries.[45]

In the case of Vietnam, the frequency is 7.1% in one study of a sample of Vietnamese reported to be from southern Vietnam[74][75] and 4.3% in a sample of Kinh people from Ho Chi Minh City in southern Vietnam,[71] but 0% or under 1% in other studies in which samples have been collected in Hanoi in northern Vietnam.[43][75][45] So, it is hard to define average frequencies.

Only some regions and ethnic groups in the continent show high frequencies. Q-M242 is found in 2.8% (3/106, all Q-M346) in Myanmar, and all the Q samples are concentrated in 18.8% in Ayeyarwady (2/11) and 7.1% Bago (1/14) regions in southwest Myanmar.[76] And, Q-M242 is found in 55.6% (15/27) in the Akha tribe in northern Thailand.[45]

Central Asia

In Central Asia, the southern regions show higher frequencies of Q than the northern ones.

In the northern regions, Q-M242 is found in about 2%[77]~6%[78][79] (average 4%) of Kazakhs. A study published in 2017 found haplogroup Q Y-DNA in 3.17% (41/1294) of a large pool of samples of Kazakh tribes; however, haplogroup Q was concentrated in the members of the Qangly tribe (27/40 = 67.5%), and it was much less common among the other tribes.[80] The Qangly tribe is related at least in name to the earlier Kankalis and probably also the Kangar union. Haplogroup Q is found in about 2% of Kyrgyz people.[47][78][79]

In the southern regions, Q-M242 is found in 5%[81]~6%[78][79] of Tajiks (Tajikistan). Karafet et al. 2001 found P-DYS257(xQ1b1a1a-M3, R-UTY2), which should be roughly equivalent to haplogroup Q-M242(xM3), in 4/54 = 7.4% of a sample of Uzbeks, apparently sampled in Uzbekistan.[82] Wells et al. 2001 found P-M45(xM120, M124, M3, M173), which should be roughly equivalent to a mix of Q-M242(xM120, M3) and R2-M479(xR2a-M124), in 20/366 = 5.5% of a pool of samples of Uzbeks from seven different regions of Uzbekistan.[78] Di Cristofaro et al. 2013 found Q-M242 in 11/127 = 8.7% of a pool of samples of Uzbeks from three different provinces of Afghanistan, including 5/94 Q-M242(xM120, M25, M346, M378), 4/94 Q-M346, and 1/94 Q-M25 (10/94 = 10.6% Q-M242 total) in a sample of Uzbeks from Jawzjan Province, whose northern border abuts the southeastern corner of Turkmenistan, and 1/28 Q-M242(xM120, M25, M346, M378) in a sample of Uzbeks from Sar-e Pol Province.[47] Wells et al. (2001) found P-M45(xM120, M124, M3, M173) in 10.0% (3/30) of a sample of Turkmens from Turkmenistan, whereas Karafet et al. (2018) found Q-M25 in 50.0% (22/44) of another sample of Turkmens from Turkmenistan, so the frequency of haplogroup Q in that country is not yet clear. However, Grugni et al. (2012) found Q-M242 in 42.6% (29/68) of a sample of Turkmens from Golestan, Iran, and Di Cristofaro et al. (2013) found Q-M25 in 31.1% (23/74) and Q-M346 in 2.7% (2/74) for a total of 33.8% (25/74) Q-M242 in a sample of Turkmens from Jawzjan, Afghanistan, so the frequency of Q-M242 may reach about 40% in Turkmens of Afghanistan and Iran who live in the areas adjacent to Turkmenistan.

Southwest Asia

Southwest Asia exhibits high frequencies of Q in northern Iran, and gradually lowering ones to the southwest.

Q-M242 accounts for 5.5% (52/938) in Iran according to Grugni 2012, which shows a large and well allocated sampling. The Q samples (52) in the study consist of various subclades such as Q* (3), Q-M120 (1), Q-M25 (30), Q-M346 (8), Q-M378 (10). The highest frequency is at 42.6% (29/68, all Q-M25) in Turkmens of Golestan, followed by 9.1% in Isfahan (Persian people), 6.8% in Khorasan (Persian people), 6% in Lorestan (Luristan, Lurs), 4.9% in Azarbaijan Gharbi (5.1% of Assyrians and 4.8% of Azeris), 4.5% in Fars (Persian people), and so on.[83] Turkmens are known as the descendants of Oghuz Turks who built many Turkic empires and dynasties. Other studies also show similar frequencies.[84][85][86]

In a study (Zahery 2011), the frequency of Q is 1.9% (3/154: all Q-M378) in Iraqis (x Marsh Arabs), and 2.8% (4/143: 1 Q-M25, 3 Q-M378) in Marsh Arabs who are known as the descendants of ancient Sumerians.[87][88]

Approximately 2.5% (4/157: 3 Q*, 1 Q-M346) of males in Saudi Arabia belong to haplogroup Q. It also accounts for 1.8% (3/164: 2 Q*, 1 Q-M346) in the United Arab Emirates and 0.8% (1/121: Q*) in Oman peoples.[89][90]

Haplogroup Q-M242 has also been found in 1.1% (1/87, Q-P36) Syrians[74] and 2.0% (18/914, 14 Q*, 4 Q-M25) in Lebanese.[91]

Approximately 2% (10/523: 9 Q*, 1 Q-M25) of males in Turkey belong to haplogroup Q.[92] In a study (Gokcumen 2008), it was found that among Turks who belong to the Afshar tribe (one of Oghuz Turks) haplogroup Q-M242 is seen with a prevalence of 13%.[93]

South Asia

Q-M242 accounts for 6.9% of Afghans in a study (Haber 2012). In this study, 18.4% (9/49: 8 Q*, 1 Q-M346) of Pashtuns, the largest ethnic group in Afghanistan, turned out to be haplogroup Q.[94] In another study (Cristofaro 2013) with a large sampling, the frequency of Q rises to 8.9% (45/507). In this study, Turkmens of Jowzjan Province which is neighboring to Turkmenistan show the highest frequency at 33.8% (25/74: 23 Q-M25, 2 Q-M346), followed by Uzbeks at 8.7% (11/144: 6 Q*, 1 Q-M25, 4 Q-M346).[47] If the results of these studies are aggregated and recalculated by population weights of each ethnic group, the frequency of Q in Afghan males will be 6.3%.[95]

In Pakistan at the eastern end of the Iranian Plateau, the frequency of haplogroup Q-M242 is about 2.2% (14/638)[96]~3.4% (6/176).[97]

In a study (Sharma2007), Q-M242 is observed in 2.38% (15/630) of Indian people belonging to different regions and social categories. What is interesting is 14/15 samples do not belong to any known subgroups of Q-M242, with 4 among them showing novel (Indian-specific) ‘ss4bp’ allele under Q-MEH2. This study also reflects the results of some former studies (Sengupta 2006, Seielstad 2003). And, the accumulated result (frequency) of 3 studies is turned out to be 1.3% (21/1615), with 11 out of 21 Q samples.[5] (For more information, see Y-DNA haplogroups in populations of South Asia)

In a regional study in Gujarat (Western India), Q-M242 was found at its highest 12% (3/25) among Nana Chaudharis while the overall percentage in Gujarat was found to be 2.8% (8/284).[98] In another study, 2.6% of Tharus in Chitwan district and 6.1% (3/49) of Hindus in New Delhi, the capital of India were found to be Q-M242 positive.[99]

In a study in which Q-M242 is just classified in P* group, P* (x R1, R2) accounts for 9.7% (23/237: Chakma 13/89, Marma 4/60, Tripura 6/88) in three ethnic groups of Bangladesh.[100] In many cases, all or most of P* (x R1, R2) means Q-M242, and thus most of P* (9.7%) samples in that study can be estimated to be Q-M242.

1.2% of Nepalese people in Kathmandu, the capital of Nepal and 3.2% of people from Tibet are in Q-M242.[42]

3.3% of Sri Lankans[74] are also in Q-M242.

Europe

Q-M242 is distributed across most European countries at low frequencies, and the frequencies decrease to the west and to the south.

Central- and Eastern Europe

In Central- Eastern Europe, Q-M242 comprises about 1.7% of males. Q-M242 is found in about 2% of Russians,[101] 1.5% of Belarusians,[102] 1.3% of Ukrainians 1.3% of Poles (Poland),[103] 2% of Czechs,[104] 1.5% of Slovaks,[105] about 2.2% of Hungarians,[106][107] 1.2% of Romanians,[108] 0.8% of Moldovans,[109] and 0.5% (4/808: 2 Q-M378, 1 Q-M346, 1 Q-M25) of Bulgarians[110] On the other hand, 3.1% of Székelys from Transylvania (who have claimed to be descendants of Attila’s Huns) turned out to be P* (xR1-M173),[111] which virtually means Q-M242. In a related DNA Project of FT-DNA, the frequency of Q-M25 in Székelys (Szeklers) reaches 4.3%.[112][113]

The Caucasus region shows a frequency at 1.2% in a study,[85] but it may reach over 4% in Azerbaijan, in that 4.9% of the neighboring Iranian Azerbaijanis harbor Q-M242.[84] It is 1.3% in Georgians and Armenians respectively, and Armenian subclades consist of Q-M378 (L245), Q-M346, and Q-M25.[114]

Northern Europe

In Northern Europe, haplogroup Q comprises about 2.5% of males. According to the Swedish Haplogroup Database, 4.1% (27/664, as of Jan 2016) of Swedish males belong to Q-M242. About 2/3 of the samples analyzed subclades in detail belong to Q1a2b-F1161/L527 and about 1/3 are in Q1a2a-L804. By county, they are distributed intensively in the southern region (Götaland,: not to be confused with Gotland), and rarely to the north. If recalculated by county-population weights, the frequency of Q in Sweden reaches 4.7%.

In Norway, Q-M242 is found in about 2.6% (~4%[115]) of males, with Q-L804 being more common than Q-F1161/L527.[116] It is observed among 1.6% of males in Denmark, 3% in the Faroe Islands (known to be related to Vikings).[117] In an article (Helgason et al.) on the haplotypes of Icelanders, 7.2% (13/181) of males in Iceland are labelled as R1b-Branch A, but they are actually Q-M242.[115][118] On the other hand, it is 0.2% in Finland,[119] 4.6% in Latvia,[120] 1.1% in Lithuania,[121] 0.5% in Estonia.

Western Europe

In Western Europe, Q-M242 is observed at very low frequencies, around 0.5% in most of the countries, such as Germany, France, United Kingdom, etc., but some regions show a little higher. It is 2.1% in Switzerland,[122] and it reaches 5.1% in Lyon (Rhône-Alpes) region of France.[123] It is about 4% in Shetland of northernmost Britain, with a place in it showing the highest figure at 8%. Shetland has been known to be a settlement of Vikings. And, surprisingly, Q-M242 in Shetland (also in some areas of Scandinavia, Faroe Islands, Iceland, and the Great United Kingdom) has turned out to be generically closely linked to the Q-M242 in Central Asia, . Also, Shetland (Norse) Q-M242 is revealed to be linked to some Q-M242 of Azeris (Azerbaijan).[115]

Southern Europe

Southern Europe also shows low frequencies of Q around 0.5%~1%, but some regions exhibits different figures. It is 1.9% in mainland Croatia, but it reaches 14.3% (13/91) in Hvar Islands and 6.1% (8/132) in Korčula.[123] Also, it is about 0.6% in Italy, but it rises to 2.5% (6/236) in Sicily, where it reaches 16.7% (3/18) in Mazara del Vallo region, followed by 7.1% (2/28) in Ragusa, 3.6% in Sciacca,[124] and 3.7% in Belvedere Marittimo.[125]

On the other hand, according to a study (Behar 2004), 5.2% (23/441) of Ashkenazi Jewish males belong to haplogroup Q-P36.[126] This has subsequently been found to be entirely the Q-M378 subclade and may be restricted to Q-L245. Also, 2.3% (4/174)[127]~5.6% (3/53)[128] of Sephardi Jews are in haplogroup Q.

Africa

Haplogroup Q is rarely found across North Africa. It is observed in 0.7% (1/147),[90] of Egyptians and in 0.6% (1/156)[85] of Algerian people. Surprisingly, it is also witnessed in 0.8% (3/381, all Q-M346) of males from Comoros which is located in between East Africa and Madagascar.

To combine the data above, Q-M242 is estimated to be in about 3.1% of males of the world.

  • Greenland
  • China
    • Hengbei site (Peng kingdom cemetery of Western Zhou period), Jiang County, Shanxi, 2800-3000YBP: 9 Q1a1-M120, 2 O2a-M95, 1 N, 4 O3a2-P201, 2 O3, 4 O*[151]
      • In another paper, the social status of those human remains of ancient Peng kingdom(倗国) are analyzed. aristocrats: 3 Q1a1 (prostrate 2, supine 1), 2 O3a (supine 2), 1 N (prostrate) / commoners : 8 Q1a1 (prostrate 4, supine 4), 3 O3a (prostrate 1, supine 2), 3 O* (supine 3) / slaves: 3 O3a, 2 O2a, 1 O*[152]
      • (cf) Pengbo (倗伯), Monarch of Peng Kingdom is estimated as Q-M120.
    • Pengyang County, Ningxia, 2500YBP: all 4 Q1a1-M120[151] (with a lot of animal bones and bronze swords and other weapons, etc.)
    • Heigouliang, Xinjiang, 2200YBP: 6 Q1a* (not Q1a1-M120, not Q1a1b-M25, not Q1a2-M3), 4 Q1b-M378, 2 Q* (not Q1a, not Q1b: unable to determine subclades):[153]
      • In a paper (Lihongjie 2012), the author analyzed the Y-DNAs of the ancient male samples from the 2nd or 1st century BCE cemetery at Heigouliang in Xinjiang – which is also believed to be the site of a summer palace for Xiongnu kings – which is east of the Barkol basin and near the city of Hami. The Y-DNA of 12 men excavated from the site belonged to Q-MEH2 (Q1a) or Q-M378 (Q1b). The Q-M378 men among them were regarded as hosts of the tombs; half of the Q-MEH2 men appeared to be hosts and the other half as sacrificial victims.
    • Xiongnu site in Barkol, Xinjiang, all 3 Q-M3
      • In L. L. Kang et al. (2013), three samples from a Xiongnu) site in Barkol, Xinjiang were found to be Q-M3 (Q1a2a1a1). And, as Q-M3 is mostly found in Yeniseians and Native Americans, the authors suggest that the Xiongnu had connections to speakers of the Yeniseian languages.[154][155] These discoveries from the above papers (Li 2012, Kang et al., 2013) have some positive implications on the not as yet clearly verified theory that the Xiongnu were precursors of the Huns.
    • Mongolian noble burials in the Yuan dynasty, Shuzhuanglou Site, northernmost Hebei China, 700YBP: all 3 Q (not analysed subclade, the principal occupant Gaodangwang Korguz (高唐王=趙王 阔里吉思)’s mtDNA=D4m2, two others mtDNA=A)[156]
      • (cf) Korguz was a son of a princess of Kublai Khan (元 世祖), and was the king of the Ongud tribe. He died in 1298 and was reburied in Shuzhuanglou in 1311 by his son. (Do not confuse this man with the Uyghur governor, Korguz who died in 1242.) The Ongud tribe (汪古部) was a descendant of the Shatuo tribe (沙陀族) which was a tribe of Göktürks (Western Turkic Khaganate) and was prominent in the Five Dynasties and Ten Kingdoms period of China, building three dynasties. His two queens were all princesses of the Yuan dynasty (Kublai Khan's granddaughters). It was very important for the Yuan dynasty to maintain a marriage alliance with Ongud tribe which had been a principal assistant since Genghis Khan's period. About 16 princesses of the Yuan dynasty married kings of the Ongud tribe.

However, these are from studies where all current branches of the Q-M242 tree have not been tested. The problematic phylogeny sampling of early studies has been demonstrated by subsequent studies that have found Q-M346, Q-M378, and Q-M25 in South Asia.

The SNPs used in the paper are P-M45, R1a1-M17, Q1a2-M3, and other xP-M45 SNPs. And the author mentions that, among ethnic groups in the paper, R1-M173 is harbored only in some eastern Siberian Udegeys and Koryaks and Native Americans. Also, R2 (distributed in India and its neighbours) cannot be found in far east Siberia. Thus, P-M45 except some samples mentioned above virtually means Q-M242 (xM3). In the paper, 35.3% of Nivkhs and 20.8% of Chukchi people and 18.2% of Siberian Eskimos are shown in P-M45, and 12.5% of Chukchis and 21.2% of Siberian Eskimos are in Q-M3. All of them can be estimated to be in haplogroup Q.

  88. According to scholars, early Sumerians called themselves 'black-headed people', and spoke an agglutinative language with the word order of SOV, which was quite different from common Semitic or Indo-European languages. Among Semitic languages, only Akkadian had SOV word order, which is due to the influence of the Sumerian language.(For more information, see Sumer, Sumerian Language, Akkadian language, and so on.) On the other hand, surprisingly, some ancient writings found in Bolivia such as Pokotia Monolith, have been interpreted with the Proto-Sumerian language. http://www.faculty.ucr.edu/~legneref/biados/texts/WintersPokotia.htm

  95. To aggregate the results of Haber 2012 and Cristofaro 2013, the frequency of each ethnic group is 33.3% (25/75) in Turkmens, followed by 8.1% (11/136) in Pashtuns, 7.6% in Uzbeks (11/144), 4.4% in Hazara, 3.0% in Tajiks. Currently, Afghans consist of Pashtun 42%, Tajik 27%, Hazara 9%, Uzbek 9%, Turkmen 3%, others 10%. Thus, if recalculated by population weights of ethnic groups, the frequency of Q in Afghans will be 6.3%.
