构建了性选择的群体遗传模型，其中，在平衡状态下，雄性通过开发昂贵的装饰品来表明其质量，而雌性则在配偶选择中支付使用装饰品的成本。结果表明，均衡的形式不受费雪过程（即女性偏好的自我强化）的影响。这是应用于性选择的障碍原理的工作模型，并将扎哈维的障碍原理置于与费舍尔过程相同的逻辑基础上，因为每个人都可以在没有另一个人存在的情况下支持性选择。提出了一种衡量这两个过程的相对重要性的方法，该方法可以应用于理论和事实。建议采用一种能够将简单遗传学和复杂生物学相结合的建模风格。
A population genetic model of sexual selection is constructed in which, at equilibrium males signal their quality by developing costly ornaments, and females pay costs to use the ornaments in mate choice. It is shown that the form of the equilibrium is uninfluenced by the Fisher process, that is, by self-reinforcement of female preferences. This is a working model of the handicap principle applied to sexual selection, and places Zahavi''s handicap principle on the same logical footing as the Fisher process, in that each can support sexual selection without the presence of the other. A way of measuring the relative importance of the two processes is suggested that can be applied to both theories and facts. A style of modelling that allows simple genetics and complicated biology to be combined is recommended.
