在雌雄异株物种中，雄性不育与雌雄同体同时出现。通常，雄性不育性状是母系遗传的，因此称为细胞质雄性不育（CMS）。核位点结合其“自己的”特定细胞质类型恢复雄性生育能力。理论上，两个适应度组成部分对于维持该育种系统很重要：雄性不育的适应度优势和恢复成本。恢复的成本据称是恢复等位基因的负面多效性效应。
In gynodioecious species, male steriles co‐occur with hermaphrodites. Usually, the male sterile trait is maternally inherited, hence it is called Cytoplasmic Male Sterility (CMS). Nuclear loci restore male fertility in combination with their ‘own’ specific cytoplasmic types. In theory, two fitness components are important for the maintenance of this breeding system: a fitness advantage of the male steriles, and costs of restoration. The costs of restoration are alleged negative pleiotropic effects of restorer alleles.
