Like Kashmiris who have higher AASI (only a bit higher) and much less steppe then Ror look more like pashtuns. And even pashtuns despite living further west have less central asian steppe then Ror. So its not just AASI. Maybe environment and natural selection played important role. Another thing to consider is west asian and steppe maternal lines drastically decreases as one move east. So for Ror/UP jat groups gene flow was mostly through males.The looks of an individual is determined by only a dozen or few dozen genes...
Yes Jatts of Haryana have the highest steppe percentage....But they also tend to have a higher Ancient Ancestral South Indian percentage, which determines their looks
The sum of Steppe percentage plus West Asian agriculturist percentage in Pashtuns and others in the Indus region is higher than the corresponding sum in India, eventhough the ones in India have a higher pure Steppe percentage
It seems 5-10 percent higher AASI component can drastically change looks
The purest Aryan group in South Asia remains the Kalash group..They even to this day follow a religion that would be considered ancestral to even the Vedas....They stopped in outside mixing by 600 BCE...This is why I thank the Durand Line the most...without the Durand Line the Kalash on the side of Pakistan would have met the same fate as the Kafiristanis did in 1890s
Technically apart from Ror/jat, rest of Indians have much less steppe then majority of Pakistanis. We tend to have higher west asian agriculturists %. How did Ror get so much steppe despite living hundreds of miles east? And from who?
