Fig 4. Sliding window PCA indicates that differentiation between A. coluzzii and A. gambiae is restricted to centromeric chromosome regions.

Fig 4

Chromosome 3 is analyzed as four non-overlapping windows of 115 uniformly spaced SNPs each, as follows: A) Telomeric and central region of chromosome 3R, B) centromeric region of chromosome 3R, C) centromeric region of chromosome 3L, and D) central and telomeric region of chromosome 3L. Sliding window analysis indicates that A. coluzzii (blue) and A. gambiae mosquitoes (red) cluster together as an apparently panmictic population when typed using non-centromeric markers. In contrast, the Goundry form (turquoise) is distinct from A. coluzzii and A. gambiae across the entire length of both chromosome arms, at both centromeric and non-centromeric sites.
