Distribution of F_ST values and π ratios calculated in 100 kb windows with 10 kb steps. (A) Distribution of F_ST values among autosome chromosomes. The red line represents the 0.01 level, and the blue line represents the 0.05 level. (B) Distribution of π ratios among autosomal chromosomes. (C) Intersection of the two methods used to identify high-quality selection regions. Data points located to the right of vertical dashed line (corresponding to the 5% right tails of the empirical θπ ratio distribution), and above the horizontal dashed line (the 5% right tail of the empirical F_ST distribution) were identified as selected regions for Wannan black pig (red points).
