If phenotypic plasticity is a trait subject to selection and evolution, we need to quantify reaction norms and to identify the potential target(s) of selection. Previously we proposed the use of polynomial coefficients as reaction norm descriptors. However, the interpretation of these coefficients is not straightforward if the reaction norm is not linear. Therefore, we instead propose the use of characteristic values to describe reaction norms. We depict such characteristic values for linear, quadratic, and logistic reaction norms, discuss how they might evolve, and illustrate their estimation using data on abdominal pigmentation of Drosophila simulans.
如果表型可塑性是一个受选择和进化影响的性状，我们就需要对反应规范进行量化，并确定选择的潜在目标。此前我们提议使用多项式系数作为反应规范的描述符。然而，如果反应规范不是线性的，这些系数的解释就不直观。因此，我们转而提议使用特征值来描述反应规范。我们描绘了线性、二次和逻辑斯蒂反应规范的此类特征值，讨论了它们可能如何进化，并使用拟暗果蝇腹部色素沉着的数据说明了它们的估计方法。
