Haplogroup O (mtDNA)

Haplogroup O mtDNA is a haplogroup derived from haplogroup N and found in Oceania.[1]

This article is about the human mtDNA haplogroup. For the human Y-DNA haplogroup, see Haplogroup O-M175.

It is one of the rarest haplogroups. As of 2022, FamilyTreeDNA reports that only 4 people are known members of the haplogroup.[2] YFull reports 5 known members, 4 of whom are from Australia, and that the haplogroup is at least 20,000 years old. [3]
