Figure 3 Selective sweep analysis of the populations from different regions. (a, b) Distribution of Pi ratios (North/SCS, SCS/North) and F ST values calculated using the sliding window approach. Data points located to the right of the vertical dashed line (corresponding to the 5% right tails of the empirical Pi ratio distribution, where the θπ ratios are 0.887 and 0.446, respectively), and above the horizontal dashed line (upper 5% tail of the F ST distribution, whereF ST is 0.183) were identified as selected regions for North populations and SCS populations (red points), respectively; (c) The distribution of selected genes (North vs. SCS) related to Gene Ontology terms; (d) Pi ratios and F ST values plot using a 10-kb sliding window of the genes (North vs. SCS) with strong selective sweep signals, and the EYS gene regions are marked in red
