Apomixes is comparable to the conditions of apogamy and apospory, which are seen in many ferns.

在许多蕨类植物中常见的无融合生无配子生无孢子生。

Homosporous ferns produce sporophytes by intra gametophytic selfing, inter gametophytic mating, or apogamy.Gametangium ontogeny, genetic load, and ploidy affect the mating system of each species.

型孢子蕨类的孢子体可经由配子体自交、异配子体交配两类配育系统或以无配生的方式产生，异配子体交配又可分为异配子体自交异配子体异交两种方式。
