It is a subgroup of haplogroup M29'Q. OriginHaplogroup Q is a descendant of haplogroup M. DistributionToday, mitochondrial DNA Haplogroup Q is found in the southern Pacific region, especially in New Guinea, Melanesia[2] and indigenous 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 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. SubcladesTreeThis phylogenetic tree of haplogroup Q subclades is based on the paper by Mannis van Oven and Manfred Kayser Updated comprehensive phylogenetic tree of global human mitochondrial DNA variation[1] and subsequent published research.
