The origins and genomic affinities of various tribal populations of India are of considerable contemporary interest. In this study, we have investigated relationships among five tribal groups inhabiting the north-eastern, eastern and sub-Himalayan regions of India. DNA samples have been analysed in respect of 25 polymorphic loci, based on which genetic affinities have been estimated. The interesting findings of this study are (i) the Tibeto-Burman speaking, morphologically Mongoloid, tribal groups of India are not genetically very homogeneous, and (ii) the Tharu, a group inhabiting the sub-Himalayan region, may indeed have undergone considerable admixture as has been postulated by some anthropologists.
印度各部落人口的起源和基因组亲缘关系在当代备受关注。在本研究中，我们调查了居住在印度东北部、东部和喜马拉雅山脉地区的五个部落群体之间的关系。对DNA样本进行了25个多态性位点的分析，并据此估计了遗传亲缘关系。本研究的有趣发现是：（i）印度讲藏缅语、形态上为蒙古人种的部落群体在基因上并非非常同质化；（ii）居住在喜马拉雅山脉地区的塔鲁族可能确实如一些人类学家所推测的那样经历了大量的混合。
