Haplogroup Q (mtDNA)

From Wikipedia, the free encyclopedia

This is an old revision of this page, as edited by 67.168.215.43 (talk) at 20:28, 14 June 2007 (Hid the text about mtDNA haplogroup Q being absent from Australian aborigines until more sources become available; some have reported a subgroup of mtDNA haplogroup Q2 among some Australian aborigines). The present address (URL) is a permanent link to this revision, which may differ significantly from the current revision.

In human mitochondrial genetics, Haplogroup Q is a human mitochondrial DNA (mtDNA) haplogroup.

Today, mitochondrial DNA Haplogroup Q is found in the southern Pacific region, especially in New Guinea and Melanesia.[1] Haplogroup Q is very diverse and frequently occurring among Papuan and Melanesian populations, with an inferred coalescence time of approximately 50,000 years before present. The frequency of this haplogroup among the populations of the islands of Wallacea in eastern Indonesia is quite high, indicating some genetic affinity between the populations of these islands and the indigenous peoples of New Guinea. Haplogroup Q has also been found, albeit at very low frequency, among modern populations of Sundaland, Micronesia, and Polynesia.

Relationship to other haplogroups

Haplogroup Q is a descendant of haplogroup M.
