a, b, The sequence identity (0.2% increments) of human only and shared duplication alignments is shown as a function of the total number of base pairs (a) and by count (b). Only single pairwise alignments were considered for shared duplications (Supplementary Fig. S8). Shared duplications were supported by human WGAC and either chimpanzee WSSD or chimpanzee WGAC. Interchromosomal (red), intrachromosomal (blue) and duplication alignments that lie within 1 s.d. of the chimpanzee–human sequence divergence (grey) are shown (Supplementary Table S13).
