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 peculiarities 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 the alleles, obtained in different periods of the outburst, continues.
1982年，乌克兰乌曼市的一群黑腹果蝇中出现了突变黄-2频率的局部增加，这种情况持续了十年。对在突变爆发期间从该种群中分离出的黄-2等位基因及其回复体的遗传特性（表型差异、突变性和互补特性）进行了研究。结果显示出现了反映等位基因结构分子差异的等位基因多样性。除了1990年从乌曼种群中分离出的突变黄，还分析了1986年至1990年从自然种群中分离出的其他性连锁基因（暗黑、微小、残翅、焦刚毛和朱红眼）的突变特性。基于这些数据得出结论：种群中存在不稳定等位基因并非突变爆发的充分条件。对在爆发不同时期获得的等位基因特性的比较分析仍在继续。
