Fig. 1From: Genome-wide detection of selection signatures in Jianli pigs reveals novel cis-regulatory haplotype in EDNRB associated with two-end black coat colorPopulation relationship and structure of Jianli pigs and other breeds tested in this study. A: NJ tree constructed by identity-by-state matrix among 153 samples. B: NJ tree based on pairwise FST values among 13 populations. C: Principle component analysis of 153 pigs using their first two components. D: Population structure of 13 pig breeds revealed by ADMIXTURE analysis (K = 2 to 11). Abbreviations for breeds are given in Table 1Back to article page
