When isolated from all contact with other flies until the opportunity to exercise mating choices, Drosophila pseudoobscura displays genetically-mediated compensatory behavior: heterokaryotypic females are more vulnerable than homokaryotes to wholly restricted contact with conspecifics. They are less able to demonstrate normal frequency-dependent sexual selection after isolation than their own homokaryotypes. However, the later the isolation in this holometabolous insect--eggs, first instars, second instars, third instars, pupae, imagoes--the fewer the behavioral effects of this isolation.
当将暗果蝇与其他果蝇完全隔离，直到有机会进行交配选择时，它们会表现出基因介导的补偿行为：异核型雌性比同核型雌性更容易受到与同种果蝇完全受限接触的影响。与自身的同核型相比，它们在隔离后表现出正常频率依赖性性选择的能力较弱。然而，在这种全变态昆虫中，隔离的时间越晚（如卵、一龄幼虫、二龄幼虫、三龄幼虫、蛹、成虫），这种隔离对行为的影响就越小。
