Fig. 2From: Whole-genome resequencing of Chinese indigenous sheep provides insight into the genetic basis underlying climate adaptationCurrent geographic populations of sheep and inferred genetic populations. In total, 173 sheep representing 41 Chinese indigenous sheep breeds were included in this study. Pink, blue, purple, yellow, and red dots indicate European, Yunnan, Tibetan, Mongolia, and Kazakh sheep groups. a Phylogenetic tree constructed by Fitch. b Population ancestry inferred by admixture analysis. c Fine-scale population structure based on the principal component analyses. d Decay of LD measured by r2 in the five groupsBack to article page
