Fig. 3From: Comparative genomics analyses of alpha-keratins reveal insights into evolutionary adaptation of marine mammalsPhylogenetic tree of type II keratins. Maximum likelihood phylogram describing phylogenetic relationships among the type II 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
