简介:目的了解福建汉族人群D2S44、D10S28、D4S163VNTR多态性,为亲权关系概率计算提供基因频率。方法采用美国Lifecodes公司提供的VNTR检测试剂盒,应用RFLP技术首次对福建省9个地市103名汉族无关个体进行D2S44、D10S28、D4S163VNTR多态性研究,并将所得基因频率与中国台湾、香港、新加坡等地区进行比较。结果福建汉族人群三位点VNTR呈高度多态性,其杂合率分别为88.6%、86.3%、90.6%,呈孟德尔经典遗传,分布符合Hardy-Weinberg平衡定律。结论福建、台湾、香港、新加坡华人互为比较,D2S44、D10S28位点基因频率没有显著性差别(P>0.500)。
