Samples distribution and population structure.
(a) Distribution of goats sampled. The IMCG, which are white in color and are used in cashmere production, were from Alashan, Inner Mongolia, in the north of China (~1304 meters’ altitude). IMCG had relatively low fecundity (~105%) compared with DBG (~272%), which are primarily used for producing meat and are raised in Chongqing in the southwest of China (267~934 meters altitude). The geographic map was drawn by R software (https://www.r-project.org/). (b) PCA plot of two goat breeds. (c) Geneticstructure of two populations. Each color represents a cluster and each bar represents an individual. (d) NJ phylogenetic tree of 12 individuals. All pictures were modified by Adobe Photoshop CS5 (http://www.adobe.com/).
