Fig. 2From: Comparative genomics analyses of alpha-keratins reveal insights into evolutionary adaptation of marine mammalsPhylogenetic tree of type I keratins. Maximum likelihood phylogram describing phylogenetic relationships among the type I keratin genes. Numbers above the nodes correspond to maximum likelihood bootstrap support values, and numbers below the nodes correspond to Bayesian posterior probabilities. Branches in blue indicated hair-type keratins, purple indicated hair follicle-specific epithelial keratins and red indicated epithelial keratinsBack to article page
