Haplogroup O (mtDNA)
Human mitochondrial DNA haplogroup
From Wikipedia, the free encyclopedia
Haplogroup O mtDNA is a haplogroup derived from haplogroup N and found in Oceania.[1] Specifically, it is found among Aboriginal Australians.[2][3] Its defining mutations are G6755A, C9140T, and G16213A.[4]
It is one of the rarest haplogroups. As of 2022, FamilyTreeDNA reports that only 4 people in their customer base who have tested their complete mitochondrial sequences are members of the haplogroup.[5] YFull reports 9 known members, 8 of whom are stated to be from Australia.[6] The haplogroup is 28 to 39 kilo years old.[7]
