父系遗传的Y染色体STR基因座多态性分析技术已广泛应用于犯罪现场生物检材的鉴定、父权鉴定、群体遗传学和人类学等领域。本文对广东省河源市龙川县277个男性个体17个Y-STR基因座的遗传多态性进行调查,为法医学研究及本地区检案提供基础数据。1材料与方法1.1样本来源根据知情同意原则,在河源龙川4个镇街中随机抽取汉族健康男性口腔拭子样本,共计277份。
Paternally inherited Y chromosome STR loci polymorphism analysis technology has been widely used in the field of bioparaffin biopsy identification, paternity testing, population genetics and anthropology and other fields. In this paper, we investigated the genetic polymorphism of 17 Y-STR loci in 277 male individuals in Longchuan County, Heyuan City, Guangdong Province, and provided basic data for forensic research and case detection in this area. MATERIALS AND METHODS A. Sample Sources According to the principle of informed consent, a total of 277 healthy oral hypo-oral swine samples were collected from 4 towns in Heyuan Longchuan.
