摘要
调查肇庆汉族人群20个常染色体STR基因座的遗传多态性,并将之与广东全省其他地级市人群的相应数据作差异性分析后发现,该地区汉族人群在20个STR基因座上均具有较好的多态性,这为法医物证相关研究和鉴定提供了基础数据;其与广东潮州、揭阳地区汉族群体的遗传差异性较大。
Through investigating the genetic polymorphism of 20 short tandem repeat(STR)loci in a Han population of Zhaoqing and analyzing the difference with the population data of Guangdong Province and other prefectures,it is found that the 20 autosomal STR loci in a population of Zhaoqing contain highly polymorphic geneticinformation,which provide basic data for forensic evidence-related research,and its genetic information shows significant difference from the Han people in Chaozhou and Jieyang,Guangdong Province.
