我们研究了复制配偶选择的进化后果，使用模型中，年轻女性的偏好受到他们观察到的老年女性的配偶选择。我们介绍了两种模式的复制，称为“单配偶复制”和“大规模复制”，对应的情况下，不成熟的女性印记的选择只有一个或一个非常大的数量的老年女性，分别。女性的交配偏好被认为只通过文化进化来进化，而男性的特征，他们的行为是通过遗传的单倍体常染色体或Y连锁基因座。结果表明，偏好和雄性性状可以快速协同进化，具有正的频率依赖优势，更常见的雄性性状等位基因。这一过程可能导致一个显示特性，降低男性的生存能力，以增加人口。大规模复制比单一配偶复制的频率依赖性更强。大量复制和在某些条件下，单配偶复制导致两个交替稳定平衡的男性性状。这两种复制模式都不支持雄性性状基因座的变异，复制使新的雄性性状表型更难传播。
We examine the evolutionary consequences of copying mate choice using models in which the preferences of younger females are affected by the mate choices that they observe older females making. We introduce two models of copying, termed “single mate copying” and “mass copying”, corresponding to situations in which immature females imprint on the choices of only one or of a very large number of older females, respectively. Female mating preferences are assumed to evolve only through cultural evolution, while the male trait on which they act is inherited either via a haploid autosomal or a Y-linked locus. Results show that the preference and male trait can rapidly coevolve, with a positive frequencey-dependent advantage to the more common male trait allele. This process can cause a display trait that lowers male viability to increase in a population. Mass copying results in stronger frequency dependence than does single mate copying. Mass copying and, under some conditions, single mate copying lead to two alterative stable equilibria for the male trait. Neither copying model supports variation at the male trait locus, and copying makes it more difficult for a novel male trait phenotype to spread.
