Figure 1: Manhattan plots showing FST-based pairwise divergence between groupings of A. gambiae.

Plots are based on mean FST in 100-SNP stepping windows for (a) M-wt versus S, (b) M-kdr versus S, (c) M-wt versus M-kdr. Grey boxes highlight the 2L genomic island region involved in introgression. Chromosomes are shown by solid grey bars and centromere positions by black circles. The position of the kdr (Vgsc-1014F) locus is shown on chromosome arm 2L.
