Abstract

Genetic studies using mitochondrial DNA ( mtDNA) have identified extensive matrilinear diversity among domestic horses. Here, we show that this high degree of polymorphism is not matched by a corresponding patrilinear diversity of the male-specific Y chromosome. In fact, a screening for single-nucleotide polymorphisms (SNPs) in 14.3 kb of noncoding Y chromosome sequence among 52 male horses of 15 different breeds did not identify a single segregation site. These observations are consistent with a strong sex-bias in the domestication process, with few stallions contributing genetically to the domestic horse
