    Did coastal South Asian populations genetically impact Southeast Asia?

    Did Southern Indian and/or coastal Eastern Indian populations have any genetic impact on either the islands of Southeast Asia or the mainland via overseas trade? Initially I was curious about the specific impact of the Cholas but now I'm more broadly interested in this question. If you have any links to literature on this topic, that would be great.

    Thank you in advance!

    Yes they did. the whole of the east coast of india, with disproportionate brahmin mixing going by the prevalence of r1a1. historical records talk of brahmins marrying local women in large amounts.

    Most "indianized" Southeast Asian groups have on average 10-15% South Asian ancestry (Bamar, Thai, Khmer, Malay, Javanese etc). Ethnic groups that were not influenced in the same way, e.g. Vietnamese (influenced by Chinese culture), as well as certain isolated Austronesian and Austroasiatic groups do not have much of it, if any. Lot of these cultures also historically maintained a caste-type system (Bamar, Javanese, Thai, Chams etc) or still do (Balinese).

    To add to the link, one of my friend's adopted a boy from Cambodia whose Y-DNA is J2b2. Likely the result of a South Asian male in ancient times.

    On another note, the dating of admixture seems to run closer to the widespread adoption of Buddhism. Even if the populations actual praxis is quite marginal, the supremacy of the Sangha instead of the Brahmins might push admixture up when Indic-descendant populations no longer had the same place in the hierarchy, and therefore no incentive for maintaining strict endogamy
