【摘要】 为分析福建、江西和浙江３省畲族之间的关系，用聚合酶链反应（ＰＣＲ）对上述３省的３代均为畲族的无关个体的载脂蛋白Ｂ（ａｐｏＢ）基因和Ｄ１７Ｓ３０位点的数目可变的串联重复（ＶＮＴＲ）序列进行研究。结果为：６个共有的ａｐｏＢＶＮＴＲ和５个共有的Ｄ１７Ｓ３０ＶＮＴＲ等位基因在３省畲族中的分布相同，为进一步在基因水平上研究他们的亲缘关系奠定了基础。本文报道的检测ＤＮＡ多态性的方法在研究民族起源、变迁和民族识别以及各民族间亲缘关系等方面有广泛的应用价值更多还原

【Abstract】 In order to analyse the consanguinity among She ethnic groups from Fujian, Jiangxi, and Zhejiang provinces, the variable number of tandem repeat( VNTR) sequences of apolipoprotein B(apoB) gene and D17S30 locus have been studied by polymerase chain reaction(PCR). The results showed that six alleles of apoB VNTR and five alleles of D17S30 VNTR were shared by She ethnic groups from those three provinces. It can be used as a part of the base for further investigating their consanguinity. The method used to detect the DNA polymorphism has practical value in studying the origin and change of different ethnic groups and their consanguinity.更多还原
