The She ethnic minority population is distributed in southern China. The origin of the She population has been controversial. The purpose of this work was to investigate the genomic diversity of She. The Chaoshan She population living in the Chaoshan Fenghuang mountain is a relatively isolated population. We detected 14 Y chromosome biallelic markers (Y-SNPs) and 6 Y chromosome short tandem repeat (Y-STR) loci in Chaoshan She people. Y-SNP analysis showed the Chaoshan She was closely related to the Chaoshan Hakka, Chaoshanese, Tujia and Gaoshan national minority. Compared with the Fujian She, the Chaoshan She maintained a more southern native genetic structure. Y-STR analysis revealed the Chaoshan She population was more closely related to the Hakka population than the other Hans. We concluded the Chaoshan She population had a closer genetic relationship with the southern national minority and Hakka Han and it may be representative of She ancestors' patrilineal genetic structure.
畲族人口分布在中国南方。畲族人口的起源一直存在争议。这项工作的目的是研究畲族的基因组多样性。生活在潮汕凤凰山的潮汕畲族人口是一个相对孤立的群体。我们在潮汕畲族人中检测了14个Y染色体双等位基因标记（Y-SNPs）和6个Y染色体短串联重复序列（Y-STR）位点。Y-SNP分析表明，潮汕畲族与潮汕客家人、潮汕人、土家族和高山族关系密切。与福建畲族相比，潮汕畲族保持了更南方的本土遗传结构。Y-STR分析显示，潮汕畲族人口与客家人的关系比其他汉族更密切。我们得出结论，潮汕畲族人口与南方少数民族和客家汉族有更密切的遗传关系，它可能代表了畲族祖先的父系遗传结构。
