Fig. 9From: Evolution of hes gene family in vertebrates: the hes5 cluster genes have specifically increased in frogsEvolutionary acquisition of hes5 genes and the hes5 cluster. Phylogenetic tree of jawed vertebrate (left). The table shows the number of hes5 genes that were classified to the hes5.1 or hes5.3 cluster and the number of hes5 genes that were not classified to the two clusters. The phylogenetic analysis was conducted using full-length amino acid sequencesBack to article page
