表型可塑性被描述为性格状态和反应规范。在相对于连续环境变量而言是异质的环境中，每个环境中对性状的选择可以通过两个表型可塑性选择模型来描述：性状状态选择模型和反应系数选择模型规范。这两个选择模型是彼此的线性变换，并且在数学上是等价的。反应规范模型似乎更简单，并产生更多的预测。用基因型-环境互作方差描述表型可塑性的遗传变异与反应范数模型有关。
Phenotypic plasticity has been described by character states and by a reaction norm. In an environment that is heterogeneous with regard to a continuous environmental variable, selection on the character within each environment can be described by two models of selection on phenotypic plasticity: a model of selection on character states and a model of selection on the coefficients of the reaction norm. The two selection models are a linear transformation of each other and mathematically equivalent. The reaction norm model seems to be simpler and to give rise to more predictions. The description of genetic variation in phenotypic plasticity by the genotype-environment interaction variance is related to the reaction norm model.
