(A) Phyogenetic tree reconstructed from 13 CR mtDNA haplotypes’ sequences of brown trout using maximum likelihood (ML) method from three (DA, AD and AT) phylogenetic lineages in the western part of the Balkans (numbers at each clade denote bootstrap probabilities); (B) Timetree inferred by applying the RelTime method to the phylogenetic tree shown in a) and the Hasegawa–Kishino–Yano substitution model, with the branch lengths below each of them and time of divergence to the right of each node.
