Phylogenetic tree of vertebrate CYP protein sequences. Maximum likelihood phylogenetic tree of round goby (Neogobius melanostomus), zebrafish (Danio rerio), human (Homo sapiens), chicken (Gallus gallus), frog (Xenopus laevis), mouse (Mus musculus), and rat (Rattus norvegicus), with 100 bootstraps, rooted with the CYP51 family. Detoxification genes CYP1–3 do not feature expansions, while a family with largely unknown function, CYP8, is expanded to six members (see gray boxes). Non-fish vertebrates are indicated in gray. Gene fragments too short for tree building but attributable to a certain family are indicated by orange half circles next to the root of the respective family
