Differential allocation occurs when reproductive investment is influenced by mate attractiveness. Recently, wide-ranging empirical support for differential allocation has been obtained. These data suggest that mates can affect the payoffs from reproduction, thus making sacrifices of reproductive value worthwhile when breeding with an attractive mate. As an example of an adaptive parental effect, the existence of differential allocation has some interesting implications for empirical studies of sexual selection and for predicting evolutionary responses to selection.
当繁殖投资受到配偶吸引力的影响时,就会出现差异分配。最近,已经获得了对差异分配的广泛实证支持。这些数据表明,配偶可以影响繁殖的收益,因此当与有吸引力的配偶繁殖时,牺牲繁殖价值是值得的。作为适应性亲代效应的一个例子,差异分配的存在对性选择的实证研究以及预测对选择的进化反应具有一些有趣的意义。
