黑色和棕色果蝇的交配持续时间不同，前者比后者更长。对这两种变种的交配实验表明，交配时间是由两性决定的。利用F-1杂交种和重组自交系进行的遗传分析表明，两个或两个以上的基因座对雄性和雌性性状的差异负责，这决定了黑色和棕色变种之间的交配持续时间，并且至少一个控制雄性性状的基因座可能位于X染色体上。棕色和黑色菌株之间雄性交配持续时间差异的基因座与雌性交配持续时间差异的基因座也有所不同。控制雄性交配时间的基因至少部分与控制身体颜色的基因有关。
Copulation duration differed between black and brown morphs of Drosophila elegans: longer in the former than in the latter. Experiments on copulation between these two morphs revealed that copulation duration was determined by both sexes. The genetic analyses using F-1 hybrids and recombinant inbred lines suggest that two or more loci were responsible for the differences in both of male and female properties for the determination of copulation duration between the black and brown morphs and at least one of the loci governing the male property was probably located on the X chromosome. It also appeared that loci responsible for the difference in copulation duration of males between the brown morph and black morph strains differed from those responsible for the difference in copulation duration of females between them. Genes controlling male copulation duration are at least partly linked with a gene controlling body coloration.
