Figure 4From: Novel intron markers to study the phylogeny of closely related mammalian speciesHuman-chimpanzee genetic distances measured in the primates tree. The different sets correspond to: a) 2750 orthologous, size-constrained introns; b) 1344 single-copy introns; c) 890 orthologous introns of neutral evolution; and d) the final set of 224 introns.Back to article page
