The South Asian populations have a mosaic of ancestries likely due to the interactions of long-term populations of the landmass and those of East andWest Eurasia. Apart from prehistoric dispersals, there are some known population movements to India. In this study,we focussed on the migration of Jewish and Parsi populations on temporal and spatial scales. The existence of Jewish and Parsi communities in India are recorded since ancient times. However, due to the lack of high-resolution genetic data, their origin and affiliation with other Indian and non-Indian populations remains shrouded in legends. Earlier genetic studies on populations of Indian Jews have found evidence for a minor shared ancestry of Indian Jews with Middle Eastern (Jews) populations, whereas for Parsis, the Iranian link was proposed. Recently, in our high-resolution study, we were able to quantify the admixture dynamics of these groups, which has suggested a male-biased admixture. Here, we added the newly available ancient samples and revisited the interplay of genes and cultures. Thus, in this study we reconstructed a broad genetic profile of Indian Jews and Parsis to paint a fine-grained picture of these ethnic groups.
南亚人群的祖先背景复杂，可能是由于该地区的长期人口与来自东亚和西亚的人口相互作用的结果。除了史前的扩散之外，还有一些已知的人口向印度的迁移。在这项研究中，我们专注于犹太人和帕西人群体在时间和空间尺度上的迁移。印度的犹太人和帕西人群体的存在可以追溯到古代。然而，由于缺乏高分辨率的遗传数据，他们的起源以及与其他印度和非印度人群的关系仍然笼罩在传说之中。早期对印度犹太人的遗传研究发现，印度犹太人与中东（犹太人）人群之间存在着轻微的共同祖先，而对于帕西人，则提出了与伊朗的联系。最近，在我们的高分辨率研究中，我们能够量化这些群体的混合动态，这表明存在着以男性为基础的混合。在这里，我们增加了新的可用的古代样本，并重新探讨了基因和文化的相互作用。因此，在这项研究中，我们重建了印度犹太人和帕西人的广泛遗传特征，以描绘这些族群的详细情况。
