Bayesian inference phylogenetic tree demonstrating the phylogenetic relationship of mitochondrial genomes of three mtDNA lineages found in the TRNP horses, and the mtDNAs of 84 modern horses.

<p>The donkey mitochondrial genome sequence (NC_001788) used as an outgroup is not displayed. Numbers shown by the Roman numeral I indicates the clades with the highest posterior probability value. The color scale refers to the clades with the posterior probabilities between 0.5 and 1.
