云南白族STR遗传多态性研究

STR polymorphism in Bai minority in Yunnan province

目的 研究我国白族STR遗传多态性。方法 通过STR复合扩增、基因扫描、基因分型调查了 98名中国白族无关个体 1 5个STR基因座等位基因分布情况。结果 共检出 1 3 4个STR等位基因 ,其频率分布在 0 .0 0 5 8～ 0 .5 799之间 ,杂合度 (H)为 0 .5 83 4～ 0 .882 8,个体识别力 (DP)为 0 .773 9～ 0 .9666,非父排除率 (EPP)为 0 .5 692～ 0 .8694,多态信息量 (PIC)为 0 .5 3 1 7～ 0 .8694。结论 为进一步研究中华民族STR遗传结构奠定了基础 ,在人类学。

Objective To study the STR polymorphism in Bai minority in China. Methods The allelic distributions of fifteen STR loci were generated through coamplification, genescan and genotype from 98 unrelated individuals.Results There were 134 STR alleles in Bai ethnic group, with its frequencies ranging from 0.0058 to 0.5799, H from 0.5834 to 0.8828, DP from 0.7739 to 0.9666, EPP from 0.5692 to 0.8694, and PIC from 0.5317 to 0.8694.Conclusion The study provides a basis for the genetic structure of Chinese ethnic groups, and also is useful for its application to anthropology and forensic science.
