X染色体STR(X-STR)基因座与常染色体STR基因座相比,由于遗传方式的差异,在某些疑难亲缘关系鉴定中会显示出较高的检验效能,可以作为常染色体STR分型的有力补充[1-2]。本文采用Investigator Argus X-12试剂盒(Qiagen,德国)对广东瑶族群体进行12个X-STR基因座的遗传多态性分析,为法医个体识别和亲子鉴定提供群体遗传学数据,评估其法医学应用效能。 Compared with the autosomal STR locus, the X chromosome STR (X-STR) locus shows high test potency in some difficult genetic relationship due to the difference of the genetic pattern, and can be used as autosomal STR typing Strong supplement [1-2]. In this study, 12 genotypes of X-STR loci were genotyped by investigator Argus X-12 Kit (Qiagen, Germany) to provide population genetic data for forensic individual identification and paternity testing, and to evaluate their forensic applications efficacy.
