Forensic physical evidence paternity testing and individual identification parameter calculating method

Abstract

The invention discloses a forensic physical evidence paternity testing and individual identification parameter calculating method. The calculation of a paternity index, a biological full-sib state consistency score and an individual identification matching probability of paternity testing in forensic practice is carried out by adopting an Excel table; when parameters are calculated, a corresponding kit and a corresponding calculation formula are found; an allele is input into a corresponding locus of the Excel table to generate the parameters. The method disclosed by invention is combined with forensic physical evidence practice, and simple and easy, efficient and accurate calculation software is designed and programmed by taking genetic data of Yunnan population and kits which are commonly used in each laboratory and have stable properties as the foundation, so that the calculation of important forensic parameters including the paternity index, the biological full-sib state consistency score and the individual identification matching probability of the paternity testing in the forensic practice and the like can be solved very well, and powerful helps and technical supports are provided for more objectively and more conveniently obtaining testing opinions.

Description

technical field [0001] The invention belongs to the field of parent-child identification, in particular to a method for parent-child identification and calculation of personal identification parameters in forensic material evidence. Background technique [0002] Forensic physical evidence is a discipline that studies the identification of biological samples related to the human body in the application of life science technology to solve cases with the purpose of providing scientific evidence. Through the inspection and analysis of human biological samples, the discipline finally achieves the purpose of personal identification and paternity test, thus providing clues for investigation and scientific evidence for trial. In the process of forming scientific evidence, an extremely important link is the formation of appraisal opinions, which rely on DNA typing results to judge whether there is a parentage relationship or whether they come from the same individual. The relevant t...
