Figure 2From: Inferring selection in the Anopheles gambiae species complex: an example from immune-related serine protease inhibitorsGenetic differentiation between populations. Arrows indicate approximate sampling locations within Africa, and letters identify species (A- An. arabiensis, G- An. gambiae, M-form and S-form). Dashed lines indicate pairs of populations for which genetic differentiation was calculated, and numbers are K ST statistics, averaged across all 32 loci.Back to article page
