Due to its geographic location, Gujarat has played a major role in assimilation of different cultures with those of the subcontinent of India and is home to a number of Indo-European speaking tribes.
This study examined the genetic structure and extent of gene differentiation in eight Indo-European speaking tribal populations of southern Gujarat in western India. It also determined if there was any residual effect of linguistic and cultural assimilation of Indo-European speaking groups on the genomic profile of the tribes under study.
Twenty autosomal DNA markers (Alu InDels and Restriction Fragment Length Polymorphisms) were analysed.
Average heterozygosity levels were high and degree of gene differentiation (G(ST) = 2%) was small, indicating that genetic drift may not have played a major role in bringing out a characteristic genetic differentiation in these groups. The genetic structure of the populations revealed that neither of these groups was overtly admixed nor completely isolated. Other analyses undertaken on the population affiliations revealed only a slight influence of Indo-European speaking populations on the tribal groups of Gujarat, but there was an overwhelming influence of Dravidian speaking groups of southern India, suggesting that genetic affinities may not necessarily be dependent on linguistic similarities.
由于其地理位置，古吉拉特邦在不同文化与印度次大陆文化的融合中发挥了重要作用，并且是一些说印欧语系语言部落的家园。
本研究调查了印度西部古吉拉特邦南部八个说印欧语系语言的部落群体的遗传结构和基因分化程度。它还确定了说印欧语系群体的语言和文化同化对所研究部落的基因组概况是否有任何残留影响。
分析了20个常染色体DNA标记（Alu插入缺失和限制性片段长度多态性）。
平均杂合度水平较高，基因分化程度（G(ST)=2%）较小，表明遗传漂变在这些群体中产生特征性遗传分化方面可能没有发挥主要作用。群体的遗传结构表明，这些群体既没有明显的混合，也没有完全隔离。对群体归属进行的其他分析显示，说印欧语系的群体对古吉拉特邦的部落群体只有轻微影响，但印度南部说达罗毗荼语系的群体有压倒性影响，这表明遗传亲和力不一定取决于语言相似性。
