Fig. 1From: Genome-wide detection of genetic structure and runs of homozygosity analysis in Anhui indigenous and Western commercial pig breeds using PorcineSNP80k dataSample information and the population genetic structure of ten pig breeds. A Geographical distributions and sample numbers of the ten pig breeds. B Principal component analysis plot for the ten pig breeds. C Phylogenetic tree of the ten pig breeds. D Admixture results (K = 2–10) for the genetic structure of ten pig breeds. The numbers on the left (under K = N) indicate cross-validation (CV) error values. Red shaded regions in (B) and (C) represent the WECPs, and blue-shaded regions represent the AHIPs. Anhui indigenous pig breeds (AHIPs): YZ, Wei pigs; WNHZ, Wannan black pigs; HZ, Huai pigs; WNHUAZ, Wannanhua pigs; LB, Six White pigs. Western commercial pig breeds (WECPs): LAN, Landrace pigs; DUR, Duroc pigs; PIE, Piétrain pigs; LWY Large White pigs; BER, Berkshire pigsBack to article page
