我们使用19个Y-SNPs对中国22个省汉族人群的Y染色体单倍型分布进行了调查。我们的数据表明，中国南方和北方汉族人群之间的Y染色体的独特模式。南方种群比北方种群更具有多态性。后者只有南方单倍型的一个子集。这一结果证实了在东亚南部和北方种族人群之间观察到的遗传差异。它支持了这样的假设，即非洲起源的现代人类的第一个定居点发生在最后一个冰河时代的东亚南部，并向北迁移导致了中国北方的人口。
We investigated the distribution of Y-chromosome haplotype using 19 Y-SNPs in Han Chinese populations from 22 provinces of China. Our data indicate distinctive patterns of Y chromosome between southern and northern Han Chinese populations. The southern populations are much more polymorphic than northern populations. The latter has only a subset of the southern haplotypes. This result confirms the genetic difference observed between southern and northern ethnic populations in East Asia. It supports the hypothesis that the first settlement of modern humans of African origin occurred in the southern part of East Asia during the last Ice Age, and a northward migration led to the peopling of northern China.
