对考古学、解剖学、语言学和遗传学数据的分析表明，中国南北方的人群之间一直存在着明显的分界线。然而，这一边界的确切位置和强度仍然存在争议。本研究利用91个群体的mtDNA数据和143个群体的Y染色体数据，系统地探讨了人类群体的空间遗传结构和南北划分界限。我们的研究结果突出了母系和父系的空间遗传结构之间的明显差异。北方群体与南方群体之间存在显著的遗传分化，其母系结构特征是沿沿着淮河和秦岭向北延伸至长江，存在明显的不间断遗传边界。在父系方面，然而，没有明显的遗传分化之间的北方和南方群体被揭示。
Analyses of archeological, anatomical, linguistic, and genetic data suggested consistently the presence of a significant boundary between the populations of north and south in China. However, the exact location and the strength of this boundary have remained controversial. In this study, we systematically explored the spatial genetic structure and the boundary of north–south division of human populations using mtDNA data in 91 populations and Y-chromosome data in 143 populations. Our results highlight a distinct difference between spatial genetic structures of maternal and paternal lineages. A substantial genetic differentiation between northern and southern populations is the characteristic of maternal structure, with a significant uninterrupted genetic boundary extending approximately along the Huai River and Qin Mountains north to Yangtze River. On the paternal side, however, no obvious genetic differentiation between northern and southern populations is revealed.
