An ordinary differential equation model for two competing populations with genetic variation in one population is presented. The degree of frequency dependence needed to produce various configurations of stable equilibria is discussed. For example, if the fitnesses are frequency independent then there may exist stable polymorphism although the genetically varying population becomes extinct in each fixation plane. Stable polymorphism where the genetically invariant population becomes extinct in each fixation plane requires frequency dependence in the fitness of the genetically invariant population.
提出了一个关于两个竞争种群的常微分方程模型，其中一个种群存在遗传变异。讨论了产生各种稳定平衡构型所需的频率依赖程度。例如，如果适应度与频率无关，那么可能存在稳定多态性，尽管在每个固定平面中遗传变异的种群会灭绝。在每个固定平面中遗传不变的种群灭绝的稳定多态性需要遗传不变种群的适应度具有频率依赖性。
