In 1982, a local increase of frequency of mutation yellow-2, which lasted for a decade, occurred in a population of Drosophila melanogaster from Uman` (Ukraine). Genetic properties (phenotypic difference, mutability, and pecularities of complementation) of alleles yellow-2, isolated from the population during the mutation outburst, and of their revertants, were studied. Allelic diversity, which reflected molecular differences in allele structure, was shown to appear. In addition to mutation yellow, isolated in 1990 from the Uman` population, mutational properties of other sex-linked genes (dusky, miniature, rudimentary, singed, and vermilion) isolated from natural populations in 1986 to 1990, were analyzed. Based on these data, the conclusion was drawn that the presence of unstable alleles in populations is not a sufficient condition for mutation outbursts. Comparative analysis of properties of yellow alleles obtained in different periods of the outburst continues. 17 refs., 4 tabs.
