In human genetics, a human mitochondrial DNA haplogroup is a haplogroup defined by differences in human mitochondrial DNA. Haplogroups are used to represent the major branch points on the mitochondrial phylogenetic tree. Understanding the evolutionary path of the female lineage has helped population geneticists trace the matrilineal inheritance of modern humans back to human origins in Africa and the subsequent spread around the globe.

Contents

The letter names of the haplogroups (not just mitochondrial DNA haplogroups) run from A to Z. As haplogroups were named in the order of their discovery, the alphabetical ordering does not have any meaning in terms of actual genetic relationships.

The hypothetical woman at the root of all these groups (meaning just the mitochondrial DNA haplogroups) is the matrilineal most recent common ancestor (MRCA) for all currently living humans. She is commonly called Mitochondrial Eve.

The rate at which mitochondrial DNA mutates is known as the mitochondrial molecular clock. It is an area of ongoing research with one study reporting one mutation per 8000 years. [2]

Phylogeny

mtDNA haplogroup tree and distribution map. The numbers are haplogroup labels, reported according to the http://www.phylotree.org/ nomenclature, and give the location of one of the mutations leading to the derived haplotype. (Only a single branch defining marker, preferably from the coding region, is shown.) The main geographic features of haplogroup distribution are highlighted with colour.

Macro-haplogroup L

Macro-haplogroup L is the most basal of human mtDNA haplogroups, from which all other haplogroups descend (specifically, from haplogroup L3). It is found mostly in Africa.

Macro-haplogroup M

Macro-haplogroup M is found mostly in Asia and the Americas. Its descendants are haplogroup M, haplogroup C, haplogroup Z, haplogroup D, haplogroup E, haplogroup G and haplogroup Q.

Macro-haplogroup N

Macro-haplogroup N is found mostly in Australia, the Americas and parts of Asia. Its descendants are haplogroup N, haplogroup O, haplogroup A, haplogroup S, haplogroup I, haplogroup W, haplogroup X and haplogroup Y, as well as macro-haplogroup R.

Macro-haplogroup R

Macro-haplogroup R is found mostly in Europe, Northern Africa, the Pacific and parts of Asia and the Americas. Its descendants are haplogroup R, haplogroup B, haplogroup F, haplogroup H, haplogroup V, haplogroup J, haplogroup T, haplogroup U and haplogroup K

Geographical distribution

A 2004 paper suggested that the haplogroups most common in modern West Asian, North African and European populations were: H, J, K, N1, T, U4, U5, V, X and W. [7]

African haplogroups: L0, L1, L2, L3, L4, L5, L6, T, U5a

Australian haplogroups: M42a, M42c, M14, M15, Q, S, O, N, P. (Refs 1, 2, 3, 4, 5, 6)

Asian haplogroups: F, C, W, M, D, N, K, U, T, A, B, C, Z, U many number variants to each section
