gnomancer

Y chromosome (paternal line)

Haplogroup O

O

The dominant lineage of East and Southeast Asia: O-M122 (Han Chinese and neighbours), O-M119 (coastal China, Taiwan, Austronesians), O-M95 (Southeast Asia).

How gnomancer finds it

The Y haplogroup is called from the Y-chromosome sites on your chip by yhaplo (ISOGG tree) with a second opinion from Yleaf on the current YFull, FamilyTreeDNA and ISOGG trees. Arrays type a few thousand Y sites, so the call stops at roughly this depth; Y sequencing (e.g. Big Y-700) is needed for a terminal subclade.

Run it on your own raw file: install gnomancer (nothing is uploaded), or ask your AI assistant with the MCP server.
