贵州汉族,苗族,布依族和水族人群线粒体DNA多态性研究

本文运用１６种限制性内切酶对来自贵州的汉族、苗族、布依族和水族的１５０个样本进行了ｍｔＤＮＡ的限制性片段长度多态性（ＲＦＬＰ）分析。共检测到３１种限制性格局（Ｒｅｓｔｒｉｃｔｉｏｎｐａｔｔｅｒｎ），其中ＨａｅＩＩ－１３型、ＥｃｏＲＶ－３型和ＰｓｔＩ－４型３种限制性格局为新报道综合这些限制性格局，共得出２８种ｍｔＤＮＡ类型（ｍｔＤＮＡｔｙｐｅ）。运用ＵＰＧ法和简约法分析了各ｍｔＤＮＡ类型之间、各人群之间的聚类关系，结果表明：水族人群的ｍｔＤＮＡ变异度较大；汉族和苗族的亲缘关系最近，布依族和水族有着较远的亲缘关系。

Mitochondrial DNA Polymorphism in the Han,Miao,Buyi,and Shui Ethnic Groups from Guizhou Province

Sixteen restriction endonucleases were used to assay the mtDNA polymorphism in the Han,Miao,Buyi and Shui ethnic groups from Guizhou province. Thirty-one restriction patterns were observed in a total of 150 subjects studied,out of which HacII-13, EcoRV-3 and PstI-4 are first reported by this paper. From all restriction patterns disclosed by l6 enzymes, twenty-eight mtDNA types were obtained.UPG method and parsimony networks were employed to analyze the clustering relationships between types or populations. Following conclusions are obtained:the mtDNA from the Shui nationality possesses the highest polymorphism; the Han and the Miao are most closely related;and the genetic relation between the Buyi and the Shui is somewhat distant.
