Unrooted molecular phylogenetic trees including the hagfish Dlx genes. The topologies and branch lengths were calculated with the neighbour-joining method. (A) Phylogenetic tree of Dlx1/4/6 (based on 155 amino acid sites). (B) Phylogenetic tree of Dlx2/3/5 (based on 106 amino acid sites). Bootstrap probabilities (NJ and ML) greater than 50 and posterior probabilities (BI) greater than 0.5 are shown at each internal branch supported by all three phylogenetic trees, as the left, middle, and right numbers, respectively. The clades of the cyclostome Dlx genes are indicated with bold lines. The hagfish genes are shown in white letters in a black box.
