ABSTRACT: Microsatellites or Short Tandem Repeats (STRs) are loci with alleles composed of tandemly repeated short DNA sequences of 2-7 base pairs in length. In the present study, the polymorphism STR loci CODIS were analyzed in 40 people with a history of crime using multiplex PCR. The 6 STRs loci included TH01, TPOX, D16S539, D18S51, CSF1PO and FGA. The result showed that the highest PD and heterozygosity belongs to allele FGA. The most polymorphism was observed in the D18S51 and FGA loci. Also the highest allele frequency was detected at locus FGA.
