    Abstract

    Gene and genotype frequencies in relation to the D1S80 locus were determined in a sample of 197 unrelated individuals (144 Caucasians and 53 Mulattoes), living in the city of São Paulo, Brazil. The Mulatto group was composed by mixed individuals who presented at least one negroid physical characteristic or declared themselves to be of mixed (Black-White) ancestry. Nineteen different alleles were detected in the Caucasian sample and 15 among Mulattoes. Alleles 18 and 24 were found to be the most common ones in the Caucasian population with frequencies of 0.173 and 0.357 respectively; the sample heterozygote frequency was estimated in 0.824. Alleles 18, 24, and 28 were found to be the most common alleles among Mulattoes with respective frequencies of 0.150, 0.349, and 0.113; the sample heterozygote frequency was 0.759. Fifty-five different genotypes were detected among Brazilian Caucasians whereas the respective figure among Mulattoes was 31. No significant deviations from Hardy-Weinberg equilibrium were found in both population samples.
