Objective To investigate the genetic polymorphisms of 10 short tandem repeats loci (D6S1043, D7S3048, D9S925, DllS2368, D14S608, D15S659, D17S1290, D20S470 and GATA198B05) in Liaoning Anshan Xiuyan Man population. Methods We used a multiplex system developed by ourselves to amplify 252 Xiuyan Man population unrelated individual's DNA. The amplified fragments were separated by electrophoresis in 3130 Genetic Analyzer. We used GeneMapper R3.2 software to analyze these results. Results The distributions of geno- type for 9 STR loci in the population were all in accordance with Hardy-Weinberg equilibrium. The polymorphism information component of the 9 STR loci was among 0.750 to 0.860; the heterozygote was among 0.794 to 0.881; the discrimination power was among 0.918 to 0.968; the probability of exclusion wase among 0.587 to 0.757; the combined probability of exclusion was 0.999 96; and the combined discrimination power was 0.999 999 999 999 1. Conclusion The 9 STR loci have high probability of exclusion and discrimination power,which can be loci available as the candidate genetic markers for population genetics and forensic practice.
