1985年英国科学家Jeffreys等人应用基于限制性片段长度多态性的多基因座探针技术(DNA finger-printing,DNA指纹),克服了传统法医物证检验鉴别机率低的缺陷,使法医学个人识别和亲子鉴定实现了从只能排除到高概率认定的飞跃,标志着法医物证检验技术新纪元的开始。然而,DNA分型技术作为一种崭新的科技手段应用于法庭审判,在世界各国引起了巨大的争论与关注。近年研究证明,应用Jeffreys的DNA指纹法进行法医物证检验有一定限制。DNA指纹分析在标准化方面的困难和对检材需求量的苛求,至今难以克服。加之,DNA指纹分析无法确定每条谱带的染色体定位以及各位点之间的独立性,其概率计算至今仍有争论。因此,大多
In 1985, British scientist Jeffreys et al. Used DNA finger-printing (DNA fingerprinting) based on the restriction fragment length polymorphism to overcome the defects of low probability of traditional forensic evidence testing and discrimination, and to make forensic personal identification and Paternity test achieved only from the leap can be ruled out to a high probability that marks the beginning of a new era of forensic evidence testing technology. However, the application of DNA typing technology as a new scientific and technological means in court trial has caused great controversy and concern in all countries in the world. In recent years, studies have shown that the use of Jeffreys DNA fingerprinting forensic evidence test has some limitations. The difficulty of standardization of DNA fingerprinting analysis and the demanding requirements of the samples have so far been insurmountable. In addition, DNA fingerprinting analysis can not determine the chromosomal location of each band and the independence between the various sites, the probability calculation is still controversial. So, mostly
