Abstract

This study presents a database related to autosomal STR DNA of population of Chhattisgarh, India and evaluates diversity of autosomal STR in the context of forensic applications and genetics.In this piece of study, allele distribution at 15 autosomal STR loci were investigated for the randomly selected 445 unrelated healthy individuals (205 females and 240 males) from various geographical regions of Chhattisgarh using AmpFlSTR(R) Identifiler(R) Plus PCR Amplification Kit. High degree of genetic polymorphism have been indicated by all the loci with observed Heterozygosity (Hobs) obtained in the range from 0.661 (TH01) to 0.852 (D2S1338). Locus FGA was observed as the most discriminatory and polymorphic with the value of 0.965 and 0850 respectively among all the studied loci. The paternity index and cumulative matching probability for the examined loci were found to be 3.7 × 105 and 3.8 × 10−18 respectively. The cumulative power of discrimination and exclusion were detected to be 1 and 0.99999764 respectively, a sign that all the loci are exceptionally polymorphic and conceivably significant in forensic applications.
