七个少数民族线粒体DNA的遗传多样性研究

Rearch on the mtDNA of seven Minority Nationalities

本文用14种限制性内切酶对来自青海的蒙古族、贵州的苗族、云南各地的傈僳族、白族、彝族。傣族和基诺族共80个样本的线粒体DNA（mtDNA）进行了限制性片段长度多态性（RFLP）分析，有9种酶检测到多态，共计48种单倍型．结果表明：彝族和白族人群的mtDNA变异度较大；在与非洲、东南亚、美洲、欧洲人群的横向比较中发现一些典型的突变位点，如：10394c和8994e．

Including 9 types of enzyme made experienment in various changing conditions and 48 types of hap lotype in all. This eassay states a specific analysis on W, adopting 14 types of restriction endonuclease found out among 80 models of mtDNA from Mongolia people in Qinhai, Miao people in Guizhou, Lisu, Bal, Dai and Jinuo People living in Yunnan province. The result reveals that the Variahon rate of mtDNA is a litile bit higher, that some typical mutation points, for example, 10394c and 8994e, are found in the cross comparison between American peo ple and Europeans.
