Look up Genomic Formation of South and Central Asia, Narasimha et al 2018
There's some nice graphics that show the relationship between all parties involved from Europa to Asia through 10k years, so its worth it even if you're only getting started with genetics. Pic related.

Says:
Narasimhan et al. (2018) conclude that ANI and ASI were formed in the 2nd millennium BCE. They were preceded by a mixture of AASI (ancient ancestral south Indians, that is, hunter-gatherers), and Iranian agriculturalists who arrived in India at ca. 4700–3000 BCE, and "must have reached the Indus Valley by the 4th millennium BCE"
i.e. well before white Yamnaya showed up, Iranians farmers and native (read: black) hunter gatherers mixed and spread through india. The Vedic race (or ANI, ancestral north indians) were descended from a mixture of fair Yamnaya and brown ANI leftovers of brown IVC.
There is no doubt the Proto-Indo-European gods they brought with them (Dyaus Pitta, Indra, Hesu, Rudra, Manu etc.) were blond and blue-eyed. Note that there are also have native gods Murugan, Krishna, Shiva etc that are traditionally considered dark. The Vedas are a clash of two cultures and if you read it (in particular the older Rig Veda) it will be evident.
Discussion of this is all good and dandy, but I just want to interject quickly with a reminder that the seed of Abraham is our first enemy, and all others come second.
