Preservation breeding

Preservation breeding is an attempt by many plant and animal breeders to preserve bloodlines of species, either of a rare breed, or of rare pedigrees within a breed.[1][2][3]

Purpose

Preservation breeding can have several purposes:

  1. Protection of genetic diversity within a species or a breed;[2][4][5]
  2. Preservation of valuable genetic traits that may not be popular or in fashion in the present, but may be of great value in the future;[1]
  3. Population or re-population of an area where a species previously existed;
  4. Support of a wild population that is defective or infected, by breeding healthy individuals and releasing them into the population in order to strengthen the overall health of the population.[6]

Mechanism

Preservation breeding can take the following forms:

  1. Selective breeding of rare breeds and rare pedigrees, particularly monitoring breeding genetics in small populations to ensure diversity is maintained as much as possible;[2]
  2. Rare breeds that suffer life-threatening genetic deficiencies can be intentionally cross-bred with other breeds that have the critical gene, in order to preserve the rare breed into the future;[1]

History

The term preservation breeding was first used by notable American Kennel Club Judges Douglas Johnson and Bill Shelton in breeder seminars for dog breeders in the early 2000's. The preservation of dog breeds and the conservancy of canine genetics started gaining more traction in the mid-2010's.

gollark: ++remind 1m test
gollark: It also appears to have ignored coral.
gollark: *How* did Reminding 2™ remind me twice and *why* did this not turn up in testing?
gollark: That's now illegal.
gollark: It just sent reminder 3200 twice. This is NOT good.
