Using QPADM models on Kamma samples show there are primarily 2 main streams in the South. All other Haplogroups are one group mainly led by H1 admixture and there is another stream of R2a people who form a different admixture. I have did a QPADM model using Parkai as the main admixture component for my sample using other haplogroups in the ITU dataset and mostly all other haplogroups including diverse ones like R1a, O2, N1b, Q, K2, C5, J2b2, J2a etc work but most of the R2a samples are failing
Passing models using ITU
Failing models using R2a in ITU
Components of admixture
As shown in the map above, all the clades in the south can be split into H dominated mix with O, L, R1a, C, N, Q, j2b2 etc.. where the R2a is the other group. And further north there is North Indian component which is probably R1a primary mixed with R2 and J in some places
