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 or if you find any broken links on this page.

Private SNPs are being removed from the tree and placed in the following category:
Private SNPs - After having been investigated, these SNPs have not met the population distribution criteria for placement on the tree. Either too few confirmed positive testers have been found OR multiple confirmed testers were confined to either a single surname or to a small group of related males.

SNPs under Investigation - Additional testing is needed to confirm adequate positive samples and/or correct placement on the tree.


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.
