Functional validation of human-specific PowerPlex® 21 System (Promega, USA) in chimpanzee (Pan troglodytes).

Of 21 STRs in PowerPlex® 21 System (Promega, USA), 19 loci amplified and found to be polymorphic. Locus Aml showed differential banding patterns in males and females similar to those seen for humans and correctly assigned sexes of known identity. Altogether, 58 different alleles were found with an average 3.05 ± 0.28 alleles per locus. Mean observed (Ho), and expected heterozygosity (He) were 0.93 ± 0.03 and 0.52 ± 0.05, respectively.
