本研究对中国闽西地区汉族600名健康无关个体进行20个常染色体STR基因座遗传多态性调查。利用直接扩增法提取模板DNA,采用Promega Power Plex21 System试剂盒进行扩增及检测。结果在20个常染色体STR基因座中共检测出250个等位基因和934种基因型,其分布符合Hardy-Weinberg平衡定律(P>0.05)。所调查的汉族人群20个STR基因座具有较好识别能力。
This study investigated the genetic polymorphism of 20 autosomal STR loci in 600 Han unrelated individuals in western Fujian. The template DNA was extracted by direct amplification and amplified with Promega Power Plex21 System kit. Results A total of 250 alleles and 934 genotypes were detected in 20 autosomal STR loci. The distribution was in accordance with the Hardy-Weinberg equilibrium (P> 0.05). The 20 STR loci of Han population surveyed have better recognition ability.
