Abstract

Several migratory waves from various origins along with cultural practices restricting marriages between people of different castes and tribes as well as continued endogamy have led to a complex and diverse society in the Indian subcontinent. Despite being widely represented in genetic studies, several interrogatives remain with regards to India's current genetic constituents and distributions, source populations and population relationships. To identify the forces that may have shaped Indian population's genetic relationships, we undertook a comprehensive comparative study of the Y-chromosomes across India utilizing Y-STR and Y-SNP chromosomal markers using the general population of Chennai in the state of Tamil Nadu as a point of reference. Our analyses identify differences in source populations for different regions within India, unique linguistic characteristics as well as demographic and cultural forces that may have shaped population structure.

摘要

几个起源不同的迁徙群体，加上限制不同种姓和部落之间通婚的文化习俗以及持续的内婚制，导致了印度次大陆形成了一个复杂多样的社会。尽管在遗传研究中得到了广泛的代表，但关于印度当前的遗传成分和分布、源种群和种群关系，仍有几个疑问。为了确定可能影响印度人口遗传关系的因素，我们利用 Y-STR 和 Y-SNP 染色体标记，对印度各地的 Y 染色体进行了全面的比较研究，以泰米尔纳德邦钦奈市的普通人群作为参考点。我们的分析确定了印度不同地区的源种群的差异、独特的语言特征以及可能影响人口结构的人口和文化力量。
