在时间和空间变化的环境中的遗传多态性的近似条件是中间的健身水平或基因功能的水平的基因座。这些条件表明，多态性将更有可能在更多变的环境中，而不太可能在恒定的环境中。生化证据证明杂合子中介假设。对自然种群的观察证实了等位酶多态性主要是由于选择作用于基因功能的环境变异。
Approximate conditions for genetic polymorphism in temporally and spatially varying environments are presented for loci which are intermediate at the level of fitness or at the level of gene function. The conditions suggest that polymorphism will be more likely in more variable environments while unlikely in constant environments. Biochemical evidence is presented to justify the assumption of heterozygote intermediacy. Observations on natural populations are cited which substantiate the claim that allozymic polymorphism is primarily due to selection acting on environmental variation in gene function.
