收集了中国33个少数民族和汉族76名男性的Y染色体，作为研究中国非重组Y染色体（NRY）遗传学的遗传材料。在全球公认的NRY单倍群中，有三个（单倍群D，C，O）在本样本中具有显著性，扩展了以前对中国遗传多样性的评估。根据地理、语言和民族历史资料，我们将调查中的33个中国少数民族分为以下四个亚群：北方、西藏、西部和南方。从新发现的直系祖先谱系单倍群O-* 的分布推断，它有M214，但没有M175，我们认为，这个最常见的中国Y单倍群的南方起源的情况是不太可能的。我们初步提出了一个西/北起源假说，表明单倍群O起源于中国西部/北部，主要在中国进化，并从那里进一步传播到整个欧亚大陆东部。嵌套分支分析详细揭示了一个多层次的，多方向的，和连续的民族混合的历史，塑造了当代中国人口。我们的研究结果为中国人口及其后代在这片土地上的迁徙和演化提供了一些新的线索，与历史记载相吻合。
Y-chromosomes from 76 Chinese men covering 33 ethnical minorities throughout China as well as the Han majority were collected as genetic material for the study of Chinese nonrecombinant Y-chromosome (NRY) phylogeny. Of the accepted worldwide NRY haplogroups, three (haplogroups D, C, O) were significant in this sample, extending previous assessments of Chinese genetic diversity. Based on geographic, linguistic, and ethnohistorical information, the 33 Chinese ethnical minorities in our survey were divided into the following four subgroups: North, Tibet, West, and South. Inferred from the distribution of the newfound immediate ancestor lineage haplogroup O-*, which has M214 but not M175, we argue that the southern origin scenario of this most common Chinese Y haplogroup is not very likely. We tentatively propose a West/North-origin hypothesis, suggesting that haplogroup O originated in West/North China and mainly evolved in China and thence spread further throughout eastern Eurasia. The nested cladistic analysis revealed in detail a multilayered, multidirectional, and continuous history of ethnic admixture that has shaped the contemporary Chinese population. Our results give some new clues to the evolution and migration of the Chinese population and its subsequence moving about in this land, which are in accordance with the historical records.
