Genetic Diversity, Molecular Phylogeny, and Selection Evidence of Jinchuan Yak Revealed by Whole-Genome Resequencing.

ABSTRACT: Jinchuan yak, a newly discovered yak breed, not only possesses a large proportion of multi-ribs but also exhibits many good characteristics, such as high meat production, milk yield, and reproductive performance. However, there is limited information about its overall genetic structure, relationship with yaks in other areas, and possible origins and evolutionary processes. In this study, 7,693,689 high-quality single-nucleotide polymorphisms were identified by resequencing the genome of Jinchuan yak. Principal component and population genetic structure analyses showed that Jinchuan yak could be distinguished as an independent population among the domestic yak population. Linkage disequilibrium analysis showed that the decay rate of Jinchuan yak was the lowest of the domestic yak breeds, in
