Phylogeny of Hox genes. Phylogenetic reconstruction of Hox genes families from amino-acid sequences present in the homeodomain and the flanking regions. The consensus tree was inferred through Bayesian phylogenetic analysis with MrBayes v3.2.2 discarding 25 % of the samples as burn-in. The branch support values are posterior probability values of Bayesian likelihood. Acr-Hox gene orthologs are highlighted by colored rectangles and the sequences used cluster with other appropriate Hox gene orthologs. The Hox1, Hox2, Hox4 and Post-2 families are strongly supported. Note that branches with posterior probability values less than 50 % are collapsed. The homeobox gene distalless was used as outgroup
