The basic mtDNA lineages in India M 66% U >11% R* <11% sum 88% The phylogeny of M lineages in India is largely a mess HVSI based median network of the M* lineages found in India. Nearly 70% of the Hg M lineages in India remain to be classified using mtDNA coding region polymorphism (M*). M2 makes up 10% of the Indian M lineages 50,600 ± 24,000 5252 8396 73,000 ± 22,900 477C 1780 8502 55,500 ± 21,000 Another 5% of the Indian M lineages belong to M6. Neither of the two M6 frequency peaks, one in Kashmir and the other in Karnataka, are reliable i) small sample size from Kashmir and ii) the presence of but one haplotype of M6a among the cast of Mukri in Karnataka.

WE specific HV, TJ, U; EE specific R9, B and I specific branches of U) in India are still unclassified derivates (R*). 20% of the R lineages belong to R5 (-MboI np 8592). 11% of the Indian R lineages is made up by Hg R6. -AluI np 12282 The spread of WE, EE and I specific maternal lineages The spread of East-Eurasian specific mtDNA haplogroups (M7, M8, M9, M10, MD, MG, R9 (incl.

This is as much as in case of two random sets of Indian populations. In contrary to 22% in the case of the Tibeto-Burman speakers, as much as 66% of the sampled AustroAsiatic speakers demonstrate mtDNA haplotypes that can also be found among the rest of Indians. random set / random set ±2% tribals / general population general population / tribals northern States / southern States southern States / northern States eastern States / western States western States / eastern States Dravidic / rest of Indians Indo-Europeans / rest of Indians Austro-Asiats / rest of Indians Tibeto-Burmans / rest of Indians Indians / Chinese Chinese / Indians Thai / Chinese Proportion of the population (group) that possess the mtDNA haplotypes in common with the other population (group).

Over half of the maternal lineages among the Tibeto-Burman speaking tribals of the eastern- and northernmost States of India belong to EE specific mtDNA lineage clusters. • MtDNA haplotype sharing analysis did not support segregation of Indian populations based on linguistics and social status (tribal vs. cast pop.) (except for the Tibeto-Burman speakers).
