  1. Shown are the numbers of fixed differences (D) between D. melanogaster and D. sechellia and the number of polymorphic sites (P) within the African population of D. melanogaster. Subscripts indicate synonymous (s), nonsynonymous (n), and intergenic (i) sites. The intergenic region is shared between the two genes (see Figure 6).
