If you mean by lower s indian then they have lower s indian then all of Pak tribes east of indus not necerarly just pak jatts. And hindu jaats in haryana seem to have even lower s indian then sikh jatts. I think reason is again mystery ne euro component, Indian punjab jatts/brahmins have mixed with haryana jaats/brahmins thats why they have high ne euro and lower caucasian then west punjabis. Its again depend on tribe since khatris look to have higher caucasian and lower ne euro. Also few sikh jatts also have higher caucasian and lower euro. But as a rule they mostly have higher euro then west punjabis.
I don't think its sampling bias because one don't need thousands of samples. And so far every Pakistani sampled have higher caucasian and lower ne euro. No idea why there is higher caucasian and lower ne euro component in west punjab to be honest.
If aryans had high ne euro in them then current day brahmins and haryana jaats are related to them. If they had higher caucasian then kalash people who have 20% are likely candidate. Remember brahmins spread out from Haryana if I am not wrong, thats why even Bengali brahmins have higher ne euro despite mixing.
seem like you don't like indian high caste regiments photos, lol pure aryan. And you can post neil nitin photo to prove how Indians look, thats will be random selection. I only posted high caste regiments because thats the best India has to offer from their tiny pool of high caste population.
and that rajput regiment are rangers or what ever but they are rajputs.
