Native American ancestry

In human population genetics, Native American ancestry refers to genetic ancestry that can be traced back to one or more Native American tribes.

Genetically, Native Americans are most closely related to East Asians.[1] Native American genomes contain genetic signals from Western Eurasia due in part to their descent from a common Siberian population during the Upper Paleolithic period.[1]

In the United States, levels of Native American ancestry differ, but among European Americans, are extremely low — just 2.7 percent carry any Native American ancestry. The genomes of self-reported African Americans averaged to 0.8% Native American ancestry, those of European Americans averaged to .18%, and those of Latinos averaged to 18.0%.[2][3]

Hispanic families in Latin America may be of Native American, European, African or Asian ancestry; many Latin Americans descend from two or more of these ancestral populations.[4]
