The Hui people are the adherents of Muslim faith and distributing throughout China. There are two contrasting hypotheses about the origin and diversification of the Hui people, namely, the demic diffusion involving the mass movement of people or simple cultural diffusion.
We collected 621 unrelated male individuals from 23 Hui populations all over China. We comprehensively genotyped more than 100 informative Y-chromosomal single nucleotide polymorphisms and 17 Y-chromosomal short tandem repeats (STRs) on those samples.
Co-analyzed with published worldwide populations, our results suggest the origin of Hui people has involved massive assimilation of indigenous East Asians with about 70% in total of the paternal ancestry could be traced back to East Asia and the left 30% to various regions in West Eurasia.
The genetic structure of the extant Hui populations was primarily shaped by the indigenous East Asian populations as they contribute the majority part of the paternal lineages of Hui people. The West Eurasian admixture was probably a sex-biased male-driven process since we have not found such a high proportion of West Eurasian gene flow on autosomal STRs and maternal mtDNA.
回族是信仰伊斯兰教的信徒，分布在中国各地。关于回族的起源和分化，有两种截然相反的假说，即涉及大规模人口迁移的人群扩散或单纯的文化扩散。
我们收集了来自中国 23 个回族群体的 621 名无关男性个体。我们对这些样本进行了全面的基因分型，包括 100 多个信息丰富的 Y 染色体单核苷酸多态性和 17 个 Y 染色体短串联重复（STR）。
与已发表的全球人群进行联合分析后，我们的结果表明回族的起源涉及对东亚土著人群的大规模同化，其祖先中约 70%可以追溯到东亚，剩下的 30%则来自西亚和欧洲各地。
现存回族群体的遗传结构主要由东亚土著人群塑造，因为他们贡献了回族父系血统的大部分。西亚和欧洲的混合可能是一种性别偏向的男性驱动过程，因为我们在常染色体 STR 和母系 mtDNA 上没有发现如此高比例的西亚和欧洲基因流。
