Selection signatures for local and regional adaptation in Chinese Mongolian horse breeds reveal candidate genes for hoof health.

ABSTRACT:

Background

Thousands of years of natural and artificial selection since the domestication of the horse has shaped the distinctive genomes of Chinese Mongolian horse populations. Consequently, genomic signatures of selection can provide insights into the human-mediated selection history of specific traits and evolutionary adaptation to diverse environments. Here, we used genome-wide SNPs from five distinct Chinese Mongolian horse populations to identify genomic regions under selection for the population-specific traits, gait, black coat colour, and hoof quality. Other global breeds were used to identify regional-specific signatures of selection.

Results

We first identified the most significant selection peak for the Wushen horse in the region on ECA23 harbouring DMRT3, the ma
