Abstract:
Objective To determine the allelic frequency distribution and genetic parameters of nine non-CODIS DNA index systems of the short tandemrepeat (STR ) loci (D2S1772, D6S1043, D7S3048, D8S1132, D11S2368, D12S391, D13S325, D18S1364, and GATA198B05). Methods A total of 353 blood samples were collected, extracted, amplified, and analyzed fromunrelated healthy individuals of Han na-tionality in Hunan Province, China. Results O ne hundred and fourteen alleles were observed in the pop-ulation with corresponding allelic frequencies ranged from0.001 0 to 0.323 0. For all the nine non-CODIS STR loci, the observed genotypic data showed no significant deviations fromthe Hardy-W einberg equi-librium. The Ho, He, PIC, D P, and PE of the studied non-CODIS STR loci ranged from0.108 0 to 0.195 0, 0.805 0 to 0.892 0, 0.770 0 to 0.860 0, 0.925 0 to 0.966 0 and 0.607 0 to 0.780 0, respectively. Conclusion N ine non-CODIS STR loci have high degrees of polymorphisms, which may be useful in in-dividual forensic identification and parentage testing in forensic practice.
