Figure 9: Evidence of directional selection from Tajima’s D across all genomic islands in each group.

From: Adaptive introgression between Anopheles sibling species eliminates a major genomic island but not reproductive isolation

Figure 9

Plots show ranks of Tajima’s D negative values (lower=more negative) for the 438 significant windows comprising islands, arrayed in order of physical position on each chromosome arm for the three sample groups: (a) S form, (b) M-wt and (c) M-kdr. Ranks are initially calculated across all 4,612 windows within each group, but only island window are shown. The red line shows the two-tailed lower 99th percentile rank used as a threshold for extreme values. Windows within the major 2L island and in the pair of very large islands of divergence on the X chromosome are highlighted in shaded boxes.
