(A) Log10 values of deletions heterozytosity of all pig breeds. (B) The LD decay of SVs, deletions, and SNPs. (C) Principal component analysis based on deletions of 66 Chinese pigs. Yellow, red, and blue circles stand for NCPG, TWPG, and SCPG, respectively. (D) Admixture analysis of deletions in Chinese pigs (K = 2, 3, and 4). (E) Frequency distribution of SVs in different groups of Chinese pigs, in which the red, blue, and yellow bars stand for specific SVs in TWPG, SCPG, and NCPG, respectively. The green bars represent SVs shared by any two groups of Chinese pigs, and black bars denote SVs shared by all three groups.
