Maximum likelihood phylogenetic trees for CTVT clades 1 to 5. Maximum likeli- hood phylogenetic trees for CTVT mtDNA in (A) clade 1 (n = 170) (B) clade 2 (n = 252) (C) clade 3 (n = 22) (D) clade 4 (n = 3) and (E) clade 5 (n = 2), rooted with haplotypes CTVT1 to CTVT5 respectively, which contain 4). Bootstrap values were calculated from 100 bootstrap replicates and are shown where bootstrap values ≥ 60. Scale bars indicate base substitutions per site. Clade 5 contains only two tumours, which are identical both to each other and to the CTVT5 haplotype; thus the tree for this clade was created separately and does not have a scale bar..
