Did you know the R1a frequency in Kayastha is less than that of Hindu Chamars? Kayasthas main line is H haplogroup at over 66% - associated with bhimta mahar dalits. The linages of Kayasth males are very different and not similar to the linage of uppercaste Brahmins and Rajputs.
For years they fooled hindus. Bad mouthing other hindus the kayasthas called them lower caste. Guess what? It turns out kayasts are less aryan than all of them!! Infact they are less aryan than some tribals of arunachal pradesh. Maturity is when you reject lies of Kayastha lala.
since when did muh r1a decide who is UC and who is LC
did you forget the historical mass impregnation and rape of LC women by OBCs? That may answer how it is higher
