The loss of genetic diversity in purebred dogs can be attributed to two major population bottleneck events: the first
occurring during domestication; and the second arising from breed formation where the repeated use of popular sires, line breeding, breeding for specific phenotypic traits, and promotion of the breed barrier rule, contributed to overall loss in genetic variation [15 - 19].
This suggests that restocking from a wild population descendant from the ancient horses
occurred during the domestication processes that ultimately led to the modern domesticated horses.
Not exact matches
This admixture could have
occurred before
domestication or
during the early stages of the
domestication process, following restocking from the wild as previously suggested (13, 32, 33).
This allowed us to pinpoint the genetic changes that have
occurred during rabbit
domestication, says SciLifeLab faculty member Leif Andersson.
Several
domestication events likely
occurred during this time, although these may have
occurred more at the instigation of the ever - adaptable cat than by any specific selective strategy of human residents.
