Figure 3From: Duplication and positive selection among hominin-specific PRAME genesPhylogenetic relationships of exons A of human and chimpanzee PRAME homologues, inferred using K S as a distance metric. Phylogenetic relationships derived using alignments of exons B and C are available as Additional files 1 and 2. Homo_9 and Homo_18 are not shown, as these pseudogenes each appears to lack exon A.Back to article page
