Phylogenetic tree of complete mtDNA genomes. Bayesian consensus phylogenetic tree produced by PHYCAS under a prior model allowing for polytomies. Clusters of sequences linked by posterior probabilities higher than 0.7 have been collapsed. Sequences belonging to cluster T are not collapsed in order to show sub groupings, and the traditional haplogroup nomenclature is shown on the right. Clades R, P, Q and T are monophyletic, but only subclades T2 and T5 are supported as definable groups amongst the previously recognized T subclades. The disparate phylogenetic positions of the Italian and the British aurochsen are indicated. All other tips refer to modern cattle genomes.
