Looking at the Y chromosomes in the Indian subcontinent, it seems that haplogroups C (found in lots of Patels) and F are the only ones with “eastern” affinity that deeply rooted in the subcontinent. Thoughts? H is found in a lot of Adivasi, but seems more related to West Eurasian populations.
This is on my mind because the Uralic populations show the strong male-based spread of eastern Y chromosomes. Finns are 60% eastern on the Y and less than 1% on the mtDNA.
