女性择偶是一个复杂的决策过程，涉及到许多与环境相关的因素。在果蝇（Drosophilamelanogaster）中，一般社会相互作用的间接遗传效应（IGEs）可以影响雌性果蝇的择偶行为，但与交配经验相关的IGEs的潜在影响却知之甚少。在这里，我们研究了与以前的交配经验相关的IGE是否对随后的女性择偶行为产生影响，并量化了与这种影响相关的加性遗传变异的程度。来自21种不同遗传背景的雌性动物与来自两种不同遗传背景之一的雄性动物一起圈养，暴露时间短（3小时）或长（48小时），并对它们随后的择偶行为进行评分。我们发现，遗传身份的前配偶显着影响了女性的后续兴趣，男性和男性的偏好。此外，半克隆分析揭示了与经验依赖性择偶行为相关的显著加性遗传变异，表明这两个参数的基因型与环境相互作用。我们讨论了这些结果的意义方面的可塑性在女性择偶行为的演变和维护有害的男性特征的变化。
Female mate choice is a complex decision‐making process that involves many context‐dependent factors. In Drosophila melanogaster, a model species for the study of sexual selection, indirect genetic effects (IGEs) of general social interactions can influence female mate choice behaviors, but the potential impacts of IGEs associated with mating experiences are poorly understood. Here, we examined whether the IGEs associated with a previous mating experience had an effect on subsequent female mate choice behaviors and quantified the degree of additive genetic variation associated with this effect. Females from 21 different genetic backgrounds were housed with males from one of two distinct genetic backgrounds for either a short (3 hr) or long (48 hr) exposure period and their subsequent mate choice behaviors were scored. We found that the genetic identity of a previous mate significantly influenced a female's subsequent interest in males and preference of males. Additionally, a hemiclonal analysis revealed significant additive genetic variation associated with experience‐dependent mate choice behaviors, indicating a genotype‐by‐environment interaction for both of these parameters. We discuss the significance of these results with regard to the evolution of plasticity in female mate choice behaviors and the maintenance of variation in harmful male traits.
