Research reveals domestication’s effects on horse genes

A study, carried out by scientists at the University of Copenhagen’s Center for GeoGenetics, detailed some 125 genes related to physical and behavioral traits favored by humans. By comparing the genomes of modern domesticated horse varieties to DNA sampled from now-extinct wild horse species, researchers were able to isolate genes that control skeletal muscles, balance, coordination, cardiac strength, fear response, and more.

Lack of Genetic Diversity in Modern Horse Populations

WA Horse Council News – Extract October 2011 Newsletter     LACK OF GENETIC DIVERSITY   An international team of researchers has used ancient DNA to produce compelling evidence that the lack of genetic diversity in modern stallions is the result of the domestication process. The published results suggest the almost complete absence of genetic diversity in modern male horses is not based on properties intrinsic to wild horses, but on the domestic process itself. Researchers sequenced Y chromosomal DNA from eight ancient wild horses dating back from around 15,000 to more than 47,000 years and a 2,800 year old… Continue reading
