About 10 years ago there was a defunct blog called the “Jat Gene.” Standard stuff. Nothing super amazing discovered, but the Jats do seem on one end of the pole. I happen to have half a dozen Jats which cluster together. You can see where they are on the PCA plots above.
– no surprise that the Jat are on the ANI end of the ANI-ASI cline
– Please note that Jat and Ror and other such groups are distinct from Pathans and especially Baloch in that the latter groups seem to have more and later gene flow/contact from West Asian groups. Perhaps this is the Islamic period? Or perhaps this is just contact due to proximity. The Baloch and Brahui in particular are distinct because they have very little AASI. The Pathan are arguably an Iranian group with South Asian inflection, but the Baloch are just plain West Asian.
– You can see at the admixture plot below. The Jat are less (marginally) European-like than the Ror, but the Treemix indicates the Ror may actually be a mix of a very European-like group with native Indian (ANI-ASI mix). The Jat are probably the same but I don’t have the samples.
