This article focuses mainly on DNA mixture from two contributors, a victim and an unknown culprit. There are areas I believe will be of interest to forensic scientists, police Jury. These identification individual in familial database searching culprit through relative. In this article, looked at individuals using Single Nucleotide Polymorphisms (SNPs) markers. SNPs starting used for identification; employed them as they produce incredible results two-person mixture. The conservative method here is the random man not excluded probability – P (RMNE) approach, inclusion generally considered frequentist approach. It was found that optimum allele frequency 0.2 required almost certain with much distortion identifying even when inbreeding up 50% population. Another interesting thing relatives suspect whom actual contributors can also identified. case where there it twice number SNP panels identify than no relative involved. And lastly, typing more helps improve therefore forensically useful results.
