Maximum parsimony tree of 164 coding-region sequences extracted from donkey mitogenomes.

The tree encompasses 161 published sequences from domestic donkeys, and one published sequence from Nubian wild ass (Equus africanus africanus, KX669267.1), all compared with the donkey reference sequence (DRS, NC_001788.1), and it was rooted by using two published sequences from wild animals (Equus africanus somaliensis; MG885769 and KM881681). The control region (D-loop: np 15464–16670) was not considered. Mutations are shown on the branches and are numbered according to DRS. Mutations are transitions unless a base is explicitly indicated. Suffixes indicate transversions (to A, G, C, or T) or reversions (@). Heteroplasmy (het) is indicated. Recurrent mutations are underlined. Insertions and deletions were disregarded. The geographic origin of each sample is indicated with specific colours; wild samples are labelled in the sample name.
