A quantitative genetic model of the joint evolution of female mating preferences and sexual dimorphism in homologous characters of the sexes is described for polygamous species with no male parental effort, such that mating preferences are selectively neutral and evolve only by indirect selection on genetically correlated characters. The male character and the homologous female character are each under stabilizing natural selection toward an optimum phenotype. At an evolutionary equilibrium the female character under natural selection is at its optimum, whereas there is a line of possible equilibria between female mating preferences and the male character. The line of equilibria may be stable or unstable, depending on the intensity of natural selection, the type of mating preferences, and the inheritance of the characters. Various mechanisms for maladaptive evolution of mating preferences and sexual dimorphism are discussed.
本文描述了一个关于雌性交配偏好与两性同源性状性二态性共同进化的数量遗传模型，适用于不存在雄性亲代投入的多配偶物种，即交配偏好是选择性中性的，仅通过对基因相关性状的间接选择而进化。雄性性状和同源的雌性性状各自都受到向最优表型的稳定自然选择。在进化平衡时，自然选择下的雌性性状处于最优状态，而在雌性交配偏好和雄性性状之间存在一系列可能的平衡。平衡线可能是稳定的或不稳定的，这取决于自然选择的强度、交配偏好的类型以及性状的遗传方式。文中讨论了交配偏好和性二态性的适应不良进化的各种机制。
