In human genetics, Haplogroup O (M175) is a Y-chromosome haplogroup. This haplogroup appears in 80-90% of all human males in East Asia, and it is almost exclusive to that region: M175 is almost nonexistent in Western Asia and is completely absent from Europe and Africa.
Haplogroup O is a descendant haplogroup of haplogroup K, and is believed to have first appeared in Siberia approximately 35,000 years ago.
Among the subbranches of haplogroup O is haplogroup O3.
