Genetics
Bengali Brahmins showed positive results for only three Y-Haplogroups R1a1, R2a and H1. Y-Haplogroups and their respective percentages are shown in the following table.
| R1a1 | R2a | H1 |
|---|---|---|
| 72.22% | 22.22% | 5.56% |
Haplogroup R1a1, which has originated either in South Asia or Central Asia or Eastern Europe is the most prevalent haplogroup amongst the Bengali Brahmins. The haplogroup is associated with the spread of the Indo-European culture in Indian sub-continent. A very high percentage of 72.22% among Bengali Brahmins which is also one of the highest found frequencies within world groups hints at its presence as a founder lineage for this caste group.
