短串联重复序列(ＳＴＲ)由2～5ｂｐ的核心序列串联重复构成。ＳＴＲ广泛分布于整个基因组中,是人类重要的遗传标记系统,现已被广泛用于法医个体识别和亲权鉴定中。本文作者对哈尔滨地区160名无关个体的Ｄ16Ｓ539、Ｄ7Ｓ820、Ｄ13Ｓ317基因座进行基因频率分布调查,其结果如下1
Short tandem repeats (STRs) consist of tandem repeats of 2 ~ 5bp core sequences. STR is widely distributed throughout the genome and is an important human genetic marker system. It has been widely used in forensic individual identification and paternity testing. The author of the 160 unrelated individuals in Harbin D16S539, D7S820, D13S317 locus gene frequency distribution survey, the results are as follows 1
