Fig. 3From: Evolution of hes gene family in vertebrates: the hes5 cluster genes have specifically increased in frogsPhylogenetic analysis of teleost hes genes. The phylogenetic tree was constructed by ML method. hes genes except for hes5 (A), only hes5 genes (B). Red and blue letters indicate zebrafish/medaka and human hes genes, respectively.
