Allele frequencies for 17 STR loci found in Identifier kit and PowerPlex (R) 16 Monoplex System were determined in a sample of 1000 unrelated individuals living in Shanghai in East China. The values of observed heterozygosity (Ho), power of discrimination (PD), probability of paternity exclusion (PE) and polymorphism information content (PIC) were calculated. All loci were in accordance with Hardy-Weinberg equilibrium (p < 0.05). The obtained frequency distributions were compared with other previously reported population data.
