Gynodioecy is apparently frequently inherited through gene-cytoplasm interactions. General conditions for the protectedness of gene-cytoplasm polymorphisms for a biallelic model with two cytoplasm types were obtained previously, and these are applied to seven special cases of gene-cytoplasm interactions controlling gynodioecy and involving dominance. It is assumed that nuclear polymorphisms cannot be maintained in one cytoplasm type only. It is held that pure cytoplasmic inheritance of gynodioecy without nuclear interactions is unlikely, and it is shown that gynodioecy with gene-cytoplasm interactions is easier to establish than purely nuclear gynodioecy, for monogenic biallelic dominant or recessive inheritance. For three special cases, a resource-allocation model with simple assumptions always leads to conditions for protectedness of gynodioecy.
雌雄异熟显然经常通过基因-细胞质相互作用遗传。先前已经获得了具有两种细胞质类型的双等位基因模型中基因-细胞质多态性保护的一般条件，并且这些条件适用于控制雌雄异熟并涉及显性的七种特殊基因-细胞质相互作用的情况。假设核多态性不能仅在一种细胞质类型中得到维持。有人认为，没有核相互作用的雌雄异熟的纯细胞质遗传是不太可能的，并且表明具有基因-细胞质相互作用的雌雄异熟比纯核雌雄异熟更容易建立，对于单基因双等位显性或隐性遗传。对于三个特殊情况，具有简单假设的资源分配模型总是导致雌雄异熟保护的条件。
