【摘要】 在92例贵州三都水族个体中,用PCR-RFLP法研究由11个单核苷酸多态位点(SNPs)组成的Y染色体单倍型频率分布,结果显示该人群的Y染色体主要为南方特异的H11和H9单倍型,两者频率高达90.22%。主成分分析结果显示其父系遗传结构与我国黎族、布依族等汉藏语系壮侗语族民族最为接近。通过Y染色体的遗传学观察与历史记载和语言学分类有较好一致性。更多还原

【Abstract】 Non recombination region of Y chromosome is a useful marker in tracing evolutionary history of paternal lineage.In the present study,total 92 individuals from Shui ethnic group in Sandu Shui Ethnic Group Autonomous County of Guizhou Province were inspected with 11 SNP sites including M7,M9,M15,M45,M89,M95,M119,M122,M130,M134 and YAP on Y chromosome.All the subjects were required to be unrelated and without intermarriage with other ethnic groups within three generations.The haplotypes were analyzed by PCR-RFLP method.Four haplotypes H5,H8,H9 and H11 were detected with frequencies of 0.054,0.044,0.315 and 0.587,respectively.Principle component indicated that the paternal lineage of Shui ethnic group is much closer to Li ethnic group of Hainan Province and Bouyei ethnic group of Guizhou Province,which belong to the group of Zhuang Dong branch of Sino Tibetan language family.In addition genetic study of Shui coincides with its linguistic distribution.更多还原
