Mating behaviour of red-eyed (wt) and brown-eyed (sepia) Drosophila melanogaster was studied under light conditions. Mating success was directly observed in mating vials and techniques usually applied in the studies of sexual selection ("female choice" and "multiple choice"). The comparison of sexual activity of mutant and wild types clearly indicates that they are not equally successful in matings. Sepia eye colour mutation decreases sexual activity of Drosophila melanogaster males, influences the preference ability of females and decreases the number of progeny from homogamic mating of the se x se type, as well as from heterogamic copulations in which sepia females take part. Non-random mating of wild type males and sepia females (in "multiple-choice" situation), with genetically and phenotypically different individuals, could be another mechanism for conservation of genetic polymorphism in natural populations.
在光照条件下研究了红眼（野生型）和褐眼（乌木色）黑腹果蝇的交配行为。在交配管中直接观察交配成功率，并采用通常用于性选择研究的技术（“雌性选择”和“多重选择”）。突变型和野生型性活动的比较清楚地表明，它们在交配中的成功率并不相同。乌木眼色突变降低了黑腹果蝇雄性的性活动，影响了雌性的偏好能力，并减少了乌木色性别类型同配交配以及乌木色雌性参与的异配交配的后代数量。野生型雄性和乌木色雌性的非随机交配（在“多重选择”情况下），与基因和表型不同的个体，可能是自然种群中遗传多态性得以保存的另一种机制。
