Phylogenetic support for alternate relationships among Msx1, Msx2, and Msx3. The three possible relationships among Msx1, Msx2, and Msx3 were directly compared using a dataset consisting of 11 taxa. Trees were generated using neighbor-joining and maximum-likelihood, with and without variation among sites (see methods). In all four instances, the favored topology grouped Msx1 with Msx2 to the exclusion of Msx3 (check marks).
