Evidence suggests that the Iranian-agriculturalist-related underwent a genetic mixture with AASI [Ancient Ancestral South Indians] somewhere between 4700 and 3000 BCE. ..."The results showed that Brahmins had genetic affinities with several foreign populations and also shared their genetic heritage with several domestic non-Brahmin groups. The study identified the deep ancient origins of Brahmins by tracing their Y-chromosome haplogroups and genetic markers on the Y-DNA phylogenetic tree. It was confirmed that the progenitors of this group emerged from at least 12 different geographic regions of the world. The study concluded that about 83% of the Brahmins in the dataset belonged to four major haplogroups, of which two emerged from Central Asia, one from the Fertile Crescent, and one was of an indigenous Indian origin." from Mahal, D.G. Y-DNA genetic evidence reveals several different ancient origins in the Brahmin population. Mol Genet Genomics 296, 67–78 (2021).
"In early 2009, a study attempted to prove that subclade Rlal reflected an indigenous origin of Brahmins in India (Sharma et al. 2009). In late 2009, another study revealed that the haplotypes of nearly all 26 ancient human specimens from the Krasnoyarsk area in Siberia dated from the middle of the second millennium BCE to the fourth century CE belonged to subclade Rlal, which is thought to mark the eastward migration of early Indo-Europeans (Keyser et al. 2009). Later, another study confirmed that subclade Rlal appeared all across Eurasia (Pamjav et al. 2012). It appears there were several migratory waves of people in haplogroup R from the Middle East and central Asia into North India....There was a convergence of haplogroups in North India starting about~ 12 kya. Some members of haplogroups R, H, and L were already inhabiting the area, mostly as hunters and gatherers. Members of haplogroup J arrived from the west and brought their knowledge of agriculture to the region. These four haplogroups (R, J, H and L) represented about 83% of the Brahmins in this study. The populations admixed and became involved with creation of the IVC in North India. After the demise of IVC, starting around the second millennium BCE, some inhabitants, mostly the newcomers, remained in the north and others dispersed to the eastern and southern parts of India, resulting in the ANI and ASI population clusters. Over time, the Brahmins expanded and spread Hinduism throughout the Indian subcontinent. As the result of religious conversions and admixture, at least 12 genetic lineages or Y-DNA haplogroups developed in this ethnic group. A larger data sample may uncover a few additional lineages."
