    Mutation in Coenzyme Q gene defines most major mtDNA haplogroups

    While analysing the mtDNA phylogeny, I noticed that most of the common, successful mitochondrial haplogroups were defined by a new mutation in the Coenzyme Q - cytochrome c reductase gene (MT-CYB) encoding the Cytochrome b protein, located between positions 14,747 and 15,887 in the mtDNA...
