From: The repertoire of G-protein-coupled receptors in Xenopus tropicalis
Phylogenetic tree of X. tropicalis , fish ( Takifugu rubripes ) and human MCHRs. The tree was calculated using the neighbour-joining method with 1000 bootstrap replicas and contained four X. tropicalis MCHRs (green branch), two fish MCHRs (blue branch) and two human MCHRs (red branch). Each X. tropicalis MCHR formed a monophyletic clade with that of humans or fish MCHR.
