ABSTRACT
Background: The basis of genetic fingerprinting and DNA profiling in forensic laboratories is the use of Short Tandem Repeats [STRs] according to local and ethnical genetics characteristics
Methods: Forensic parameters and allele frequencies for 15 autosomal STRs in 100 unrelated individuals from Khuzestan province, south Iran were determined. PCR was carried out for amplification of STRs and Gene Mapper ID software was used for genotyping and allelic analyzing
Results: The Power of Exclusion [PE] varied between 0.332 [TPOX] and 0.768 [FGA]. With exception of the THO1 [0.020], TPOX [0.014] and D18S51 [0.003], other STRs showed no deviation from the Hardy-Weinberg equilibrium [p>0.05]
Conclusion: Out of 15 STRs, 12 repeats seemed to be more useful and more powerful tools in identity and paternity determination for our studied population. Variation in our data analysis revealed that effective use of these 15 STR loci in forensic cases needed to be localized by collection and analysis of population data from the general population
