Objective:
To investigate the genetic polymorphisms of 15 STRs loci in Chinese East Mongolian population.
Methods:
DNA samples from 105 unrelated individuals in Chinese East Mongolian population were screened by Power Plex 16 System and ABI3100 Genetic Analyzer.
Results:
The genotype frequencies of these 15 STR loci meet the Hardy-Weinberg expectation. The Matching probability of 15 STRs loci were between 0.0084-0.2169, discriminating power (DP) at 0.7831-0.9916, heterozygosity (H) at 0.5619-0.9231, power of exclusion (PE) at 0.4490-0.8444, polymorphism information content (PIC) at 0.5438-0.9178. The total DP of 15 STRs loci is 0.9999999999998.
Conclusion:
Our results showed that the 15 STRs loci of Power Plex 16 System are valuable STR loci genetic marker system having high DP and are useful in forensic case work in Chinese East Mongolian population.
