贵州从江侗族Y-DNA及线粒体DNA 序列多态性分析

为分析贵州从江侗族父系及母系遗传结构，探讨其起源及迁徒, 通过聚合酶链式反应-限制性片段长度多态性(PCR-RFLP), 研究贵州从江侗族无亲缘关系个体由10个单核苷酸位点(SNPs)组成的Y染色体单倍型及11个单核苷酸位点组成的线粒体DNA单倍群频率。结果显示, 从40份男性样本的Y-SNP基因分型中，得到H6 、H11、H14 共3种单倍型；H11的频率为92.5%；通过对线粒体DNA基因分型，得到6种单倍群，有75%的个体能明确分类其所携带的单倍群特征，说明贵州从江侗族父系遗传构成相对简单。通过主成分分析，证明贵州从江侗族与其他的壮侗语族人群相聚，母系遗传结构复杂，无C单倍群分布可能为该民族特征之一。Abstract: To study the patrilineal and matrilineal genetic structure and the origin of Dong Ethnic of Congjiang Guizhou. Study the distribution of Y-chromosome haplotypes which consisted of 10 SNPs of Y-DNA and mtDNA haplogroups consisted of 11 SNPs by using PCR-RFLP method. The result is three haplotypes H6,H11,H14 were detected, the frequency of H11 is 92.5%. Six haplogroups were identified by mtDNA analysis, 75% of the people can be identified. The patrilineal genetic structure of Dong of Guizhou is simple, Principle component indicated that the structure is closer to Zhuang-Dong branch of Sino-Tibetan language family. The matrilineal genetic structure of Dong of Guizhou is complicated.

The Sequence Polymorphism of Y-chromosome DNA and mtDNA of Dong Ethnic of Congjiang, Guizhou

In order to explore the patrilineal and matrilineal genetic structure and the origin of Dong Ethnic of Congjiang in Guizhou province, the distribution of Y-chromosome haplotypes which consisted of 10 SNPs of Y-DNA and mtDNA haplogroups consisted of 11 SNPs were studied by using PCR-RFLP method.The result showed three haplotypes H6,H11,H14 were detected, the frequency of H11 is 92.5%.Six haplogroups were identified by mtDNA analysis, 75% of the people can be identified.The patrilineal genetic structure of Dong of Guizhou is simple, principle component indicated that the structure is closer to Zhuang-Dong branch of Sino-Tibetan language family.The matrilineal genetic structure of Dong of Guizhou is complicated.
