33.15及33.6探针对中国人DNA指纹图的研究

The study of 33. 15 and 33. 6 probe about DNA finger print of chinese

目的统计用33．15及33．6探针对中国人进行DNA指纹图检验的群体调查资料，为实际案件的检验提供理论依据。方法应用33．15及33．6探针为中国北京地区无关群体的血液进行DNA指纹图分析。结果应用33．15探针检验15人的DNA指纹图，无关个体间相关机率为1．03×10-15，两无关个体间出现同一谱带的平均概率0．176；应用33．6探针检验19人的DNA指纹图，无关个体间相关机率为1．53×11-11，两无关个体间出现同一港带的平均概率为0．187；两探针均符合孟德尔遗传规律，均具有组织同一性。结论本研究结果可应用于法医物证检验的亲子鉴定及个体识别。

Objective To evaluate the legal practicality of 33. 15 and 33. 6 probe in DNA fingerprint of Chinese population, and providing theorist basis for the legal test. Methods Blood sample were randomly collected in Bejing area. The DNA fingerprint of the blood sample were analyzed using 33. 15 and 33. 6 probe. Results Using 33. 15 probe test the DNA finerprint of 15 persons, the relative probability of random sample is 1. 03 × 10-15,the average probability of appearing a same bend between two random sample is 0. 176; Using 33. 6 probe test the DNA fingerprint of 19 persons, the relative probability of random sample is 1. 53 × 10-11, and the average probability of appearing a same bend between two random sample is 0. 187; Both of these two probe conform to the genetic laws of Mendel and have tissue identity. Conclusion The results suggest that 33. 15 and 33. 6 probe can be used in paternity test and identification of biological evidence of forensic medicine.
