Figure 5. Selection in the bonobo–chimpanzee common ancestor and chimpanzees.

a, Diversity in chimpanzee and bonobo around the region on chromosome 3 devoid of ILS. b, Regions where bonobos fall outside the variation of chimpanzee upstream of the MHC. The MHC region is not plotted because the SNP density is sparse there as a result of duplications. Five regions among the 50 longest regions are shown in yellow. Red points show posterior probabilities >0.8.
