Figure 2

Evolutionary relationships among relaxin-like peptides. Topology shown is a consensus tree based on MP (maximum parsimony), ML (maximum likelihood) and NJ (neighbour-joining) analysis of the amino acid alignment shown in figure 1. Consensus tree was produced and edited using TreeView to correlate topology with known genomic information about the family. Human insulin used as an outgroup. Where possible, confidence values are shown at branches: * >50%, ** >75%, all other branches are inferred. Hsa = Homo sapiens, Pt = Pan troglodytes, Mmul = Maca mulatta, Mm = Mus musculus, Rn = Rattus norvegicus, Cf = Canis familiaris, Ss = Sus scrofa, Re = Rana esculenta, Me = Macropus eugenii, Xl = Xenopus laevis, Xt = Xenopus tropicalis, Dr = Danio rerio, Tr = Takifugu rubripes, Gg = Gallus gallus, Om = Oncorhynchus mykiss.
