ＤＹＳ390是位于Ｙｐｔｅｒ Ｙｑｔｅｒ上以 4个核苷酸为重复单位的短串联重复 (ＳＴＲ)位点 ,不同的人群已发现有 3～ 8等位基因[1] 。而在法医实际工作中要求使用与被鉴定者相应的群体资料[2 ] ,因此本文通过调查 12 8名无关男性个体 ,获得ＤＹＳ390位点在广东汉族群体中的基
DYS390 is a short tandem repeat (STR) site that is 4 nucleotides in length on the Ypterter Yqter and has been found to have 3-8 alleles in different populations [1]. However, in the actual work of forensic medicine, it is required to use the group data corresponding to the appraised patients [2]. Therefore, by investigating 128 unrelated male individuals, we obtained the base of DYS390 locus in Guangdong Han population
