A study of genetic polymorphism of the STR loci D20S85 and D6S477 in Han population living in Wuhan / 法医学杂志

ABSTRACT

OBJECTIVE@#The genetic polymorphism of two STR loci, D20S85 and D6S477, were studied in 280 unrelated Chinese individuals in Wuhan.@*METHODS@#The PCR amplified products were analyzed by PAGE and silver staining.@*RESULTS@#10 and 9 alleles were observed in these two STR loci, and the discriminating power (DP) were 0.9085 and 0.9127 respectively. No deviations from Hardy-Weinberg equilibrium were found. The two STR loci had been successfully applied to individual identification and paternity testing.@*CONCLUSION@#The results demonstrated that the two loci were useful for forensic identification.
