“…The geographical distribution of the studied populations, their sample sizes, ethnic and linguistic affiliations, subsistence patterns, and their data source are given in Table 1 and their geographical locations are shown in Figure 2. The current study utilizes our recently published allele frequency data, of 15 autosomal STR markers, on the six Adi tribes of Arunachal Pradesh (Krithika et al, 2005(Krithika et al, , 2007a, the population and the methodology details of which are given in our previous publications (Krithika et al, 2005(Krithika et al, , 2007a Further, to understand the phylogenetic relationships between the different TB-, AA-, and DR-speaking populations of India, the published STR data of the six Adi sub-tribes was compared with the reported allele frequency data (for nine common STR loci) of 40 linguistically and geographically diverse tribal populations (Chattopadhyay et al, 2001;Kashyap et al, 2002;Sahoo and Kashyap, 2002;Sarkar and Kashyap, 2002;Trivedi et al, 2002;Gaikwad and Kashyap, 2003;Maity et al, 2003;Rajkumar and Kashyap, 2003;Sitalaximi et al, 2003;Langstieh et al, 2004;Banerjee et al, 2005;Singh et al, 2006;Thangaraj et al, 2006;Bindu et al, 2007).…”

An understanding of the genetic affinity and the past history of the tribal populations of India requires the untangling of the confounding influences of language, ethnicity, and geography on the extant diverse tribes. The present study examines the genetic relationship of linguistically (Dravidian, Austro-Asiatic, and Tibeto-Burman) and ethnically (Australian and East Asian) diverse tribal populations (46) inhabiting different regions of the Indian subcontinent. For the purpose, we have utilized the published data on allele frequency of 15 autosomal STR loci of our study on six Adi sub-tribes of Arunachal Pradesh and compared the same with the reported allele frequency data, for nine common autosomal STR loci, of 40 other tribes. Phylogenetic and principal component analyses exhibit geography based clustering of Tibeto-Burman speakers and separation of the Mundari and Mon-Khmer speaking Austro-Asiatic populations. The combined analyses of all 46 populations show clustering of the groups belonging to same ethnicity and inhabiting contiguous geographic regions, irrespective of their different languages. These results help us to reconstruct and understand three plausible scenarios of the antiquity of Indian tribal populations: the Dravidian and Austro-Asiatic (Mundari) tribes were possibly derived from common early settlers; the Tibeto-Burman tribes possibly belonged to a different ancestry and the Mon-Khmer speaking Austro-Asiatic populations share a common ancestry with some of the Tibeto-Burman speakers.

“…Further, to understand the genetic relationships between Adi sub-tribes and other neighboring Tibeto-Burman speaking populations, the generated autosomal STR data of Adi was compared with the published allele frequency data (for the nine common loci) of other sixteen Tibeto-Burman speaking populations from north (Ladakh) and northeast (Mizoram, Manipur, Sikkim, Nagaland and Meghalaya) India [39] – [44] . Also the observation that Tibeto-Burman speakers of the Indian subcontinent share similar physical features with that of the East and Southeast Asian populations instigated us to comprehend the genetic status of Tibeto-Burman speakers of India (including Adi) amidst the linguistically diverse but physically akin populations of East/Southeast Asia.…”

A Microsatellite Guided Insight into the Genetic Status of Adi, an Isolated Hunting-Gathering Tribe of Northeast India

Tibeto-Burman populations of India provide an insight into the peopling of India and aid in understanding their genetic relationship with populations of East, South and Southeast Asia. The study investigates the genetic status of one such Tibeto-Burman group, Adi of Arunachal Pradesh based on 15 autosomal microsatellite markers. Further the study examines, based on 9 common microsatellite loci, the genetic relationship of Adi with 16 other Tibeto-Burman speakers of India and 28 neighboring populations of East and Southeast Asia. Overall, the results support the recent formation of the Adi sub-tribes from a putative ancestral group and reveal that geographic contiguity is a major influencing factor of the genetic affinity among the Tibeto-Burman populations of India.

DNA samples of 948 individuals belonging to 27 populations from southern Andhra Pradesh were analyzed for nine AmpFlSTR Profiler Plus loci. The nature and extent of genomic diversity within and between these populations have been examined with reference to socioeconomic and geographic affiliations. The results suggest that the average heterozygosity is uniformly high in these populations (Ͼ0.80) and that the patterns of allele distributions are similar across the populations. The value of the coefficient of gene differentiation and the AMOVA and structure analysis results suggest that these populations are highly homogeneous. The neighbor-joining tree constructed using either D A or F ST distances suggests no intelligible pattern of population clusters based on ethnohistoric or geographic affiliations. All these observations suggest either a common recent origin of these populations or extensive gene flow across the populations that erased the original genetic differences. Given strict endogamy, the latter explanation can hold only if there has been unauthorized or unrecognized gene flow transecting the social boundaries. Nevertheless, the regression plot of average heterozygosity versus distance from the centroid (R ii), based on Harpending and Ward's (1982) model, and the genetic distances computed between different hierarchical groups within Andhra Pradesh tend to support this conjecture. Overall, the results suggest lack of a significant degree of genetic stratification that is consistent with social stratification in Andhra Pradesh. Furthermore, the neighbor-joining tree based on comparative data from other Indian and continental populations brings out a single and compact cluster of all the Andhra populations that is clearly separated from the rest.
