遵循A.贝特曼，我们确定了生殖力和交配成功之间的关系，在交配系统的运作的中心特征。利用数量遗传学领域的选择理论，我们将性选择梯度定义为繁殖力和交配成功率之间关系的平均斜率，并展示了如何从数据中估计它。我们认为，性选择梯度的关键是了解性选择的强度是如何影响配偶供应，父母的投资，和性别比例。
Following principles used by A. J. Bateman, we identify the relationship between fecundity and mating success as the central feature in the operation of mating systems. Using selection theory from the field of quantitative genetics, we define the sexual selection gradient as the average slope of the relationship between fecundity and mating success and show how it can be estimated from data. We argue that sexual selection gradients are the key to understanding how the intensity of sexual selection is affected by mate provisioning, parental investment, and sex ratio.
