摘要
调查了DYS19基因在中国北方汉人群体中的基因频率分布(0.013～0.516),观察到6个等位基因,各等位基因分布存在明显的地域性差异,并对陈旧、微量、降解的生物检材具有良好的适用性.
In this report, allele frequency for DYS19 was determined by PCR amplification and subsequent poly-acrilamide gel electrophoresis from unrelated China Northern Hans population. 6 alleles was detected with the frequency ranging from 0. 013-0. 516. There is obvious difference among alleles frequency from different populations. Applied to the test of blood stain, stain mixed by sperm and vaginal fluid, human tissue, ect. This method showed excellent adaptability to the examination of stale, ultratrace, degraded biological evidence.
