The origin and diversification of Muslim Hui people in China via demic or simple cultural diffusion is a long-going debate. We here generated genome-wide data at nearly 700,000 single nucleotide polymorphisms (SNPs) from 45 Hui and 14 Han Chinese individuals collected from Guizhou province in southwest China. We applied principal component analysis (PCA), ADMIXTURE, -statistics, , and analysis to infer the population genetic structure and admixture history. Our results revealed the Guizhou Hui people have a limited amount of West Eurasian related ancestry at a proportion of 6%, but show massive genetic assimilation with indigenous southern Han Chinese and Tibetan or Tungusic/Mongolic related northern East Asians. We also detected a high frequency of North Asia or Central Asia related paternal Y-chromosome but not maternal mtDNA lineages in Guizhou Hui. Our observation supports the cultural diffusion has played a vital role in the formation of Hui people and the migration of Hui people to southwest China was probably a sex-biased male-driven process.
中国穆斯林回族的起源及通过人口迁徙或单纯文化传播实现的多样化是一个长期存在的争议话题。我们在此生成了来自中国西南部贵州省收集的45名回族个体和14名汉族个体的近70万个单核苷酸多态性（SNP）的全基因组数据。我们应用主成分分析（PCA）、ADMIXTURE、-统计、和分析来推断群体遗传结构和混合历史。我们的结果显示，贵州回族有6%的比例具有有限的与西欧亚相关的祖先成分，但与南方汉族和与藏族或通古斯/蒙古相关的北方东亚人表现出大量的基因同化。我们还在贵州回族中检测到与北亚或中亚相关的父系Y染色体频率较高，但母系线粒体DNA谱系并非如此。我们的观察结果支持文化传播在回族形成过程中发挥了至关重要的作用，并且回族向中国西南部的迁移可能是一个以男性为主导的性别偏向过程。
