From: Genome-wide analysis reveals adaptation to high altitudes in Tibetan sheep
Description of the location and genetic relationships of samples.
(A) Sampling and habitats of the seven Tibetan sheep breeds. The map was created using the R package ‘maptools’, version: 0.8–37, URL: http://r-forge.r-project.org/projects/maptools/. (B) Plots for the first (Component 1) and second (Component 2) dimensions revealed the clustering of all individuals. (C) Genome-wide admixtures inferred by STRUCTURE 2.3.4. The results from K = 2 are shown; (D) Neighbour-joining (NJ) phylogenetic tree for the seven breeds based on pairwise FST. Each population is represented by a different symbol and colour label: high-altitude breeds are indicated in red and low-altitude breeds are indicated in blue. The abbreviations for the seven breeds are shown in Supplemental Table S1.
