Allele frequencies of nine STR loci--D16S539, D7S820, D13S317, CSF1PO, TPOX, TH01, F13A01, FESFPS and vWA--in the population from Alagoas, northeastern Brazil.

The polymorphism of nine STR loci has been studied in a sample of 598 individuals from the population of Alagoas, Northeastern Brazil. Determination of the allele frequencies as well as of several commonly used statistics in forensic and paternity testing were defined. The most polymorphic loci were TH01 and D7S317. The exact test demonstrated that the nine loci analyzed in the population have no deviation from Hardy-Weinberg equilibrium (P > 0.05).
