Phylogeny and nuclear gene haplotypes A phylogenetic tree based on mitochondrial Cyt b (1140 bp). Bayesian posterior probabilities (BPP) from BI analysis/ultrafast bootstrap supports (UBP) from ML analysis are noted beside nodes. Scale bars represent 0.05 nucleotide substitutions per site. The numbers at the tips of species name correspond to the ID numbers listed in Table 2 B haplotypes inferred based on the nuclear gene RAG1.
