In the present study, we analyzed 1,686 samples from 31 tribal populations of India for the mitochondrial DNA 9-base-pair deletion/insertion polymorphism, and characterized them based on the relevant mitochondrial DNA coding-region single nucleotide polymorphisms and hypervariable region I motifs, to test the genetic origins of the ethnically and linguistically heterogeneous Austro-Asiatic tribes of India. A comparative analysis of our results with the existing data suggests multiple origins of Austro-Asiatic tribes in India, and particularly the Asian and non-Asian origins of the Mon-Khmer and the Mundari populations. We also identified a novel subclade of haplogroup B in the Mon-Khmer Khasi tribes that distinguishes them from the Nicobarese, indicating two different waves of migration of the Mon-Khmer tribes in India.
在本研究中，我们分析了来自印度31个部落群体的1686份样本，以检测线粒体DNA 9碱基对缺失/插入多态性，并根据相关的线粒体DNA编码区单核苷酸多态性和高变区I基序对其进行特征分析，以检验印度种族和语言各异的南亚语系部落的遗传起源。将我们的结果与现有数据进行比较分析表明，印度南亚语系部落有多个起源，特别是孟高棉语族和蒙达里人群体的亚洲和非亚洲起源。我们还在孟高棉卡西部落中鉴定出单倍群B的一个新分支，该分支将他们与尼科巴人区分开来，这表明孟高棉部落在印度有两波不同的迁徙浪潮。
