Genetic Polymorphism of 9 STR loci in Chaoxian National Minority of China
|
Abstract:
In order to enrich the Chinese genetic database,nine polymorphic loci of STR,such as D3S1358,vWA,FGA,TH01,TPOX,CSF1PO,D5S818,D13S317 and D7S820 were studied. Based on STR gene scan marked by fluorescence,91 unrelated Chinese Chaoxian individuals were observed.81 alleles and 196 genotypes were found.The corresponding gene frequency and genotype frequency were 0.0055-0.4615 and 0.0110-0.9890 respectively.The genogypes frequency of nine STR loci was good with the Hardy-Weinberg equilibrium (P approximately 0.05). The statistical analysis of nine STR loci showed the following: PIC (polymorphic information content) >or=0.6863, H (heterozygosity) >or=0.6919, DP (discrimination power) >or=0.8301, EPP (probability of paternity exclusion) >or=0.8590. The data studied can be used in Chinese population genetic studies and forensic medicine applications.
