(A) Sequential mutational phylogenetic tree of 2959 mtDNA coding region sequences. The full tree is available in PDF format at http://www.mitomap.org/mitomap-phylogeny.pdf. All mutations are transitions except where indicated. Black polymorphisms represent nonsynonymous mutations (amino acid, position, amino acid, gene), red synonymous mutations (gene), green tRNA or rRNA mutations (gene), blue indicates non-coding nucleotides in the coding region and underlined yellow represent pathological mutations. Large blue letters indicate a haplogroup designation and large black letters allow for navigation of the tree at low magnification. Numbers in black below the final polymorphism are the bibliographic references and sequence identifiers. For example, 4(55) indicates Howell's article (4 is the code for this article) and 55 is the number of the sequence in the article). The bibliographic references are available on the mitomap website.
