We have reviewed models dealing with the maintenance of male-sterility under different modes of inheritance. For females to remain among hermaphrodites requires cytoplasmic information determining male-sterility and nuclear information restoring male-fertility. Such a nuclear-cytoplasmic polymorphism can be maintained at equilibrium given certain assumptions. However this equilibrium result may be irrelevant because gynodioecious populations are usually not at equilibrium, and because founder effects may give rise to high frequencies of females, due possibly to the fact that populations are often very different from one another genetically. The genetic structure of such a species depends on the frequency of females. Females are obligate outbreeders and usually produce more seeds than hermaphrodites. These two traits are beneficial to a group where females are present, in terms of effective size and seed output, although they are not, themselves, causes of the occurrence of females. Nuclear-cytoplasmic gynodioecy may lead to dioecy.
我们回顾了处理不同遗传模式下雄性不育维持的模型。对于雌性要在雌雄同体中留存，需要决定雄性不育的细胞质信息和恢复雄性可育性的核信息。在某些假设下，这种核质多态性可以维持在平衡状态。然而，这个平衡结果可能并不相关，因为雌全异株种群通常并不处于平衡状态，而且奠基者效应可能导致雌性出现高频率，这可能是由于种群在遗传上往往彼此差异很大。这样一个物种的遗传结构取决于雌性的频率。雌性是专性异交者，通常比雌雄同体产生更多种子。就有效大小和种子产量而言，这两个特征对有雌性存在的群体是有益的，尽管它们本身并不是雌性出现的原因。核质雌全异株可能会导致雌雄异株。
