We describe allelic variation at 28 gene loci in natural populations of D. willistoni. Seventy samples were studied from localitis extending from Mexico and Florida, thourgh Central America, the West Indies, and tropical South America, down to South Brazil. At least several hundred, and often several thousand, genomes were sampled for each locus. We have discovered a great deal of genetic variation. On the average, 58% loci are polymorphic in a given population. (A locus is considered polymorphic when the frequency of the most common allele is no greater than 0.95). An individual fly is heterozygous, on the average, at 18.4 loci. - Concerning the pattern of the variation, the most remarkable finding is the similiarity of the configuration of allelic frequencies from locality to locality throughout the distribution of the species. Our observation support the conclusion that balancing natural selection is the major factor responsible for the considerable genetic variation observed in D. Willistoni. |
