The global spread of Oriental Horses in the past 1,500 years through the lens of the Y chromosome.

ABSTRACT: Since their domestication, horses have accompanied mankind, and humans have constantly shaped horses according to their needs through stallion-centered breeding. Consequently, the male-specific portion of the Y chromosome (MSY) is extremely uniform in modern horse breeds. The majority of stallions worldwide carry MSY haplotypes (HT) attributed to an only ~1,500-y-old, so-called, "Crown" haplogroup. The predominance of the Crown in modern horse breeds is thought to represent a footprint of the vast impact of stallions of "Oriental origin" in the past millennium. Here, we report the results of a fine-scaled MSY haplotyping of large datasets of patrilines comprising 1,517 males of 189 modern horse breeds, covering a broad phenotypic and geographic spectrum. We can disentangle the multilayered
