Molecular phylogenetic trees of CTNNB1 genes. Maximum-likelihood trees of CTNNB1 genes were constructed with the long alignment for 20 tetrapod species (a) and the short alignment for 26 squamate species (b). Bootstrap values (>50 %) are shown on each node. Classification is shown on the right side of species. Blue and pink bars in b show clades of Z and W homologs of caenophidian species, respectively
