Figure 4. Percentage ancestry based on ancestry informative markers (AIMs) in Anopheles gambiae individuals from Guinea Bissau.

Figure 4

Stacked bars show percentage of ancestry found in whole genome sequenced individuals sampled in two coastal (Safim N = 5, Antula N = 12) and one inland locality (Leibala, N = 4) estimated using AIMs identified from genome-wide comparisons between samples from a more typical region of infrequent hybridization17. Percentage ancestry is based on 93 autosomal (a) and 236 chromosome-X (b) AIMs, each scored as being homozygous for A. gambiae (green) or A. coluzzii (red) or heterozygous/admixed (purple). (c) Position and genotype of chromosome-X AIMs. Each AIM was genotyped as 0 = A. coluzzii homozygote, 0.5 = A. coluzzii/gambiae heterozygote or 1 = A. gambiae homozygote. Shaded areas correspond to the >3 Mb region (dark grey) homozygous for for A. gambiae AIMs, which increases to >4 Mb (light grey) if a single heterozygous AIM is included.
