Figure 4From: Evolution by selection, recombination, and gene duplication in MHC class I genes of two Rhacophoridae speciesMinimum numbers of putative MHC class Ia loci in amphibian species. The simplified phylogenetic tree of amphibian species with a deduced number of MHC class Ia loci is based on the amphibian pedigree shown in [42]. The putative number of loci is shown above the corresponding branches.Back to article page
