Phylogeny of mammalian RLN2 and INSL4 genes. Tree generated using Tree-Puzzle using a gamma distribution, the Dayhoff model of substitution and 10 000 puzzling steps. Confidence values are shown as percentages on each branch. The INSL4 branch (labeled A on the tree) was tested for positive selection. Hsa = Homo sapiens, Mm = Mus musculus, Rn = Rattus norvegicus, Ss = Sus scrofa, Me = Macropus eugenii, Mmul = Maca mulatta, Cd = Camelus dromedaries, Gc = Galago crassicaudatus, Pt = Pan troglodytes, Ggo = Gorilla gorilla, Ph = Papio hamadryas, Fc = Felis catus, Cf = Canis familiaris, Oc = Oryctolagus cuniculus, Ma = Mesocricetus auratus, Ec = Equus caballus.
