Figure 5. Bayesian phylogenetic tree of MHC class II A genes.

The fish MHC class II A sequence (Onmy-DAA; AFP94173) is used as an outgroup. A bracket on the right shows the DAA gene lineage of the MHC genes from Crocodylia identified in the current study and previous publications as described in Materials and Methods. This gene lineage is named with ‘DAA’ (an abbreviation for MHC class II A), following Klein et al. [86]. Support on branches is indicated by posterior probabilities (PP = 0–1).
