About us

Y-DNA Haplogroup O Project is a group for users to compare their DNA results and discuss their significance. The Project is intended for everyone who belongs to haplogroup O (O, O1a, O1b, O2, and their subgroups). Many participants of the project belong to O2, the major lineage of China. It is found throughout East and Southeast Asia. This lineage also occurs in central and northern Asia at low frequencies, as well as throughout the south Pacific. It has been hypothesized that this lineage may have spread through the south Pacific in the same wave as haplogroup O1a.
