Genome-wide selection signals. Selection signals for A populations TZP and ZD and B populations TZG and ZD. The green and red areas at the top of the figures indicate the 5% of genomic regions with lowest and highest Pi ratios, respectively, and the orange areas on the right of the figures indicate the 10% of genomic regions with highest Fst. The red and purple areas in the center of the figures indicate the intersections of these top Fst and Pi regions, which constitute candidate loci under positive selection, with the purple areas indicating regions under selection in A population TZP and B population TZG
