Petit（1951,1954,1958）在黑腹果蝇中观察到，突变型和野生型果蝇的交配成功率是两种类型在培养中相对频率的函数。通常，当基因型占多数时，频率较低的雄性比相同基因型的雄性获得交配的频率更高。然而，在一种情况下（突变体，白色），当白色罕见和频繁时，交配成功率都是最高的，而在中等频率下，它在交配中处于劣势。Ehrman, Spassky, Pavlovsky, and Dobzhansky（1965）和Ehrman（1966, 1968）在d.p uloobscura中观察到明显相同的现象。罕见基因型的交配优势不仅存在于突变体中，也存在于不同基因排列的携带者、不同地理来源的菌株、甚至同一菌株在不同温度下生长的果蝇中。Spiess（在Ehrman， 1966和1968a中）发现，在persimilis中也有罕见类型的交配优势。pseudobscura和persimilis都表现出交配优势
Petit (1951, 1954, 1958) observed in Drosophila melanogaster that the mating success of mutant and wild type flies is a function of the relative frequencies of the two types in cultures. Usually the less frequent males achieve mating more frequently than do males of the same genotype when it is a majority. In one case (that of the mutant, white), the mating success was, however, highest both when white was rare and when it was frequent, while at intermediate frequencies it was at a disadvantage in mating. Ehrman, Spassky, Pavlovsky, and Dobzhansky (1965) and Ehrman (1966, 1968) observed apparently the same phenomenon in D. pseudoobscura. Here the mating advantage of rare genotypes was found not only for mutants but also for carriers of different gene arrangements, strains of different geographic origin, and even for flies of the same strain grown at two different temperatures. Spiess (in Ehrman, 1966, and 1968a) found mating advantages of rare types also in D. persimilis. Both D. pseudoobscura and D. persimilis exhibit the mating advantages of
