Phylogenetic relationships between mtDNA haplotypes.

<p>The tree shows the results for Bayesian Inference (BI) and Maximum Likelihood (ML) analyses. Posterior probability and bootstrap values are reported on each tree node. Both phylogenetic reconstructions showed the occurrence of two main clades A and B, subdivided respectively into four (A1, A2, A3, A4) and three (B1, B2, B3) sub-clades.
