A genetic study of 15 STR loci in Chinese East Mongolian population

Abstract

Abstract: Objective To investigate the genetic polymorphisms of15STRs loci in Chinese East Mongo-lian population.Methods DNA samples from105unrelated individuals in Chinese East Mongolian popu-lation were screened by Power Plex16System and ABI3100Genetic Analyzer.Results The genotype fre-quencies of these15STR loci meet the Hardy-Weinberg expectation.The Matching probability of15STRs loci were between0.0084～0.2169,discriminating power(DP)at0.7831～0.9916,heterozygosity(H)at0.5619～0.9231,power of exclusion(PE)at0.4490～0.8444,polymorphism information content(PIC)at0.5438～0.9178.The total DP of15STRs loci is0.9999999999998.Conclusion Our results showed that the15STRs loci of Power Plex16System are valuable STR loci genetic marker system having high DP and are useful in forensic case work in Chinese East Mongolian population.
