Strains of Drosophila melanogaster having different alcohol dehydrogenase (Adh) genotypes (FF, FS, or SS) were assembled in a mating chamber in varying ratios, and the mating successes were recorded. In experiments with a 25:25 ratio, the FF males succeeded in mating more than did FS and SS males, while the FS males surpassed the SS males. As for the females, FF also surpassed SS. In experiments with a 5:45 or 45:5 ratio, some differences from the 25:25 ratio occurred, but in these cases the rare genotypes were at a disadvantage. In one case, female genotypes (FF vs. SS) displayed a difference in mating latency time, but male genotypes did not. The findings did not suggest that rare genotype mating advantage and overdominance in mating success play a role in the maintenance of the Adh polymorphism.
将具有不同乙醇脱氢酶（Adh）基因型（FF、FS或SS）的黑腹果蝇品系以不同比例放入交配室，并记录交配成功率。在25:25比例的实验中，FF雄性比FS和SS雄性成功交配的次数更多，而FS雄性超过了SS雄性。对于雌性而言，FF也超过了SS。在5:45或45:5比例的实验中，与25:25比例的实验出现了一些差异，但在这些情况下，稀有基因型处于劣势。在一个案例中，雌性基因型（FF与SS）在交配潜伏时间上表现出差异，但雄性基因型没有。这些发现并不表明稀有基因型交配优势和交配成功中的超显性在维持Adh多态性中起作用。
