对广州地区汉族人群DYS19、DYS389Ⅰ/Ⅱ、DYS390基因座基因多态性分布进行调查,获得了上述基因座各种单倍型频率。为进一步充分利用Y-DNA STR的多态信息,提高Y-DNA STR单倍型的个体识别能力,增加检测基因座是一个重要方面。本文作者对另一Y-DNA STR基因座DYS392进行了研究。
The genetic polymorphisms of DYS19, DYS389Ⅰ / Ⅱ and DYS390 loci in Han population of Guangzhou were investigated. The haplotype frequencies of these loci were obtained. In order to further utilize the polymorphic information of Y-DNA STR and improve the individual identification ability of Y-DNA STR haplotype, it is an important aspect to increase the detection loci. The authors studied another Y-DNA STR locus, DYS392.
