Analysis of D1S1656 polymorphisms in Hu'nan Chinese Han population / 中国现代医生

ABSTRACT

Objective To get the genetic information and forensic parameters for the STR locus of D1S1656 in Hu'nan Chinese Han population . Methods All 451 unrelated individuals of Hu'nan Chinese Han population were selected to analyze genetic polymorphisms by using the Powerplex 21 system kit. The deviation of allele frequencies from Hardy-weinberg equilibrium was tested and the forensic parameters were counted by software. Results The marker of D1S1656 showed no significant deviation from Hardy-weinberg expectations, and 16 alleles were found with Power of Discrimination was 0.954 and Power of Exclusion 0.667. Conclusion The STR marker of D1S1656 present rich polymorphisms in Hu'nan Chinese Han population and could provide effective application in forensic field.
