Phylogenetic relationships of the coding sequences of the homologous genes in black grouse, chicken, turkey, quail and golden pheasant. The phylogenetic trees are constructed with the Neighbor-joining method. Numbers next to the branch points indicate the bootstrap values as percentages of 1000 replicates. The stars indicate the tree topology is the same as that of neutral makers.
