Fig. 6From: Evolution of hes gene family in vertebrates: the hes5 cluster genes have specifically increased in frogsComparison with hes gene locus among Xenopus (A), spotted gar (B) and elephant shark (C). Pentagon arrows show genes with the 5′–3′ direction. Magenta shows hes gene and magenta with a broken line is a pseudo gene. Orange square shows the hes5-1 cluster region. Orange and blue square shows the hes5.1 and hes5.3 cluster region, respectivelyBack to article page
