Inhuman mitochondrial genetics,haplogroup Qis ahuman mitochondrial DNA (mtDNA) haplogrouptypical forOceania.It is a subgroup of haplogroupM29'Q.

Origin

[edit]

Haplogroup Q is a descendant ofhaplogroup M.

Distribution

[edit]

Today, mitochondrial DNA Haplogroup Q is found in the southernPacific region,especially inNew Guinea,Melanesia[2]andindigenous Australians.[3]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 ofWallaceain 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 at higher frequencies, among modern populations ofSundalandbut in moderate frequenciesMicronesia,andPolynesia.In Southeast Asia it is found in lower frequencies.Malaysians1.8%,[4]It's also found inIndonesians,Filipinos(especially inSurigaonon peopleit's 4.17%[5]),Balinese1.2%,Borneans1.3%,[6]
