Phylogenetic analysis of DupA and DupB in monkey and ape species. DupA and DupB blocks for each species are indicated by "A" or "B," respectively, following the species name. With the exception of the orangutan (indicated by rectangle), all apes showed separate clades for DupA and DupB (indicated by circles). This provides strong support for an orthologous relationship between DupB and the monkey microsatellite-containing region. Clustered phylogenetic placement of the orangutan duplicated regions is consistent with a gene conversion event occurring between the two copies.
