Fig. 7. Pattern of increased localized introgression (detected using d_f) at the Alba locus among Alba species compared to non-Alba species using trios binned into three groups: (i) Alba-Alba, (ii) Alba-colored, and (iii) color-color.

(A) The sliding window analysis of introgression (d_f, 500 SNP windows) was calculated for each of the trios that had significant levels of genome-wide introgression estimated by positive D (shown in Fig. 1F). These trios were then grouped according to the wing color of the introgressing species in positions P2 and P3. (B) Number of trios that had higher d_f across the Alba locus than the 95th percentile for its chromosome. Note that only Alba individuals from C. crocea and C. eurytheme were used, which deflates the number of color comparisons.
