Figure 2.

(A) Venn diagram showing shared and lineage-specific duplications among four primate genomes. Estimates were based on identifying regions of excess read-depth to the human assembly genome. Numbers underlined are copy-number corrected to avoid the bias of nonhuman-specific SDs. (B) Assignment of duplications and rate estimation of Mbp/Myr for each branch. Note the excess of duplication rate in the branch leading to the common ancestor of human and chimpanzee (Marques-Bonet et al. 2009).
