{{stub}}=== Mithocondrial DNA Haplogroups === The same rationale and possibilities as given in Y-DNA Haplogroups apply, with the difference than Mithocondrial DNA (mtDNA) is transmitted trough the female line, and contrary to Y-DNA both males and females are able to test for it (even though it is female inherited, meaning that the mtDNA of a male is completely inherited from the mother).
