Regel 107: === Dominante sporofyt === Als de sporofyt overheerst spreekt men van '''heteromorfe~~'''~~ generatiewisseling met dominante sporofyt'''. Dit type cyclus komt voor bij enkele algen (diverse [[Bruinwieren]], [[Groenwieren]]), enkele [[slijmzwammen]], bepaalde groepen [[schimmels]] (enkele [[Chytridiomycota]]) en bij [[varens]], [[Naaktzadigen]] (gymnospermen) en [[Bloemplanten]] = [[Bedektzadigen]]).
