Description
C2b1a2a (M77) is a subclade of C2b1a2 (M48) within the Mongolic C2b1a branch. It represents a further diversification of the non-Star-Cluster Mongolic C2b lineages, found among Mongolian, Manchu, and northern Chinese populations. The M77 marker defines a Bronze Age clade that co-existed alongside the Star Cluster (C2b1a1) on the Mongolian Plateau without undergoing the same medieval founder-effect explosion.
Interesting Fact
C2b1a2a (M77) carriers share the same Bronze Age Mongolic ancestry as the Star Cluster lineage but represent the 'ordinary' patrilineal background of Mongolian populations — men whose lines survived through everyday demographic processes rather than imperial conquest.
