Genetic Diversity, Adaptation, Wild Introgression, and Coat Color Mutation of Golden Yak
Animal Research and One Health, EarlyView.Genetic diversity, adaptation, wild introgression, and coat color mutation of golden yak from two populations on the Qinghai‐Xizang Plateau. ABSTRACT The golden yak lives on the Qinghai‐Xizang Plateau with a golden coat and adapts to high altitudes and strong ultraviolet environment. The golden coat is a prominent phenotype in many domesticated species,
