Y-DNA Haplogroup O and its Subclades - 2007
The entire work is identified by the Version Number and date given on the Main Page.   Directions for citing the document are given at the bottom of the Main Page.
Version History     Last revision date for this specific page: 17 October 2007

Because of continuing research, the structure of the Y-DNA Haplogroup Tree changes and ISOGG does its best to keep the tree updated with the latest developments in the field. The viewer may observe other versions of the tree on the Web. Email Alice Fairhurst if the differences need clarification.

NOTES:

Y-DNA haplogroup O probably originated in East Asia and later migrated into the South Pacific. The lineage expanded into Taiwan (high frequency in the aboriginal Taiwanese), Indonesia, Melanesia, Micronesia, and Polynesia.

O3 is the predominant sub-group in China. The O1 and O2a lineages are found in Southeast Asian populations of Malaysia, Vietnam, Indonesia and southern China. The O2b sub-group is of high frequency in the Japanese and Korean populations.
