Genetic polymorphisms of 23 Y-chromosomal short tandem repeats (Y-STR) were investigated by PowerPlex® Y23 System in 328 unrelated male participants from Jieyang, Guangdong Province of China. A total of 293 haplotypes were obtained, and the haplotype diversity (HD) and discrimination capacity (DC) were 0.9991 and 0.8933, respectively. By comparing Jieyang population with nine other populations, Jieyang Han showed close genetic relationships with southern China-related Han populations. In conclusion, our study increased the Y-chromosome haplotype reference database and could provide useful information for forensic investigation and population genetics.
对 328 名来自中国广东省揭阳市的无关男性个体的 23 个 Y 染色体短串联重复序列（Y-STR）的遗传多态性进行了研究，使用的是 PowerPlex® Y23 系统。共获得 293 种单倍型，单倍型多样性（HD）和判别能力（DC）分别为 0.9991 和 0.8933。通过将揭阳市人群与其他 9 个人群进行比较，揭阳市汉族与中国南方汉族人群具有密切的遗传关系。总之，本研究增加了 Y 染色体单倍型参考数据库，可为法医学调查和群体遗传学提供有用的信息。
