Maternal Ancestry of Malayalis - III

Since I have already decided that my matrilineage migrated via south-west coastal India, I thought of extending that idea to other haplogroups based on inconclusive data on predominance of certain haplogroups in certain regions. However, this method could still be true as Kerala was supposedly one of the last regions to be inhabited in South India.So, it basically was a sink region for different migrations.

M derived Haplogroups:

M25:

M33: From Indus regions to Kerala via South-West India

M2/M2a/M2b - From East via South-East India. Or migrated from Bengal region to Kerala

M3/M3b - From Indus regions to Kerala via South-West India

M5 - From Indus regions to Kerala via South-West India

M64 - From Indus regions to Kerala via SW India

M30 -  From Indus regions to Kerala via SW India

M6 - From Indus regions to Kerala via SW India

M8/M8c - From East Asia or SE Asia and through trade?

C4a1 - From East Asia or SE Asia and through trade?

N derived Haplogroups:

N1d: Via South-West India

B5a: From South-East Asia and through trade

R21: From SE Asia and through trade

R5: From East via SE India 

R6: From North-West via South-West India

U1/U1a - From North-West via South-West

U4 - From North-West via South-West

U7 - From North-West via South-West

HV14 - From North-West via South-West
