From: Mitogenomic diversity and phylogeny analysis of yak (Bos grunniens)
A total of 155 mitotypes of neighbor-joining trees in yaks. The reliability of the tree topology was assessed by 1000 bootstrap replicates. I represents branch 1, II represents branch 2, and III represents branch 3; A, B,and C represent the haplogroups. h represents the Huanhu yak, y represents the Yushu yak, x represents the Xueduo yak, q represents the Qilian yak, and p represents the Pamir yak. The remaining sequences were downloaded from National Center for Biotechnology Information and detailed in Supplementary Table S2.
