本文的主要贡献是，首先，阐明了各种措施之间的关系选择和它们的关系，预测方程的进化变化。我们表明，选择的机会（相对适应度的方差）的地方上界的数量，任何字符的平均值可以通过定向选择。其次，我们提供了几种解决方案来分析多个选择集的问题（例如，性选择与自然选择）。我们展示了如何定向选择的总效果可以被划分为部分对应于特定的选择情节或健身组件。选择的机会不能如此容易地划分，因为适应度分量之间的协方差。我们提出了一个相当复杂的分区，但在特定的应用程序中可能是有用的。
The primary contributions of this paper are, first, an elucidation of the relationship between various measures of selection and their relationships to predictive equations for evolutionary change. We show that the opportunity for selection (variance in relative fitness) places an upper bound on the amount that the mean of any character can be shifted by directional selection. Second, we offer several solutions to the problem of analyzing multiple selection episodes (e.g., sexual versus natural selection). We show how the total effect of directional selection can be partitioned into parts corresponding to particular selection episodes or fitness components. The opportunity for selection cannot be so readily partitioned because of covariances between fitness components. We present a rather complex partitioning which may nevertheless be useful in particular applications.
