Inbreeding flowers
WebIn flowering plants, autogamy has the disadvantage of producing low genetic diversity in the species that use it as the predominant mode of reproduction. This leaves those species … WebInbreeding, also called selfing, is the union of gametes derived from a single individual. In flowering plants, inbreeding may occur either within a single flower, known as autogamy (intrafloral selfing) or between flowers derived from one individual, known as geitonogamy. (The genetic product of autogamy is identical with that of geitonogamy.)

WebAutogamy is a system maximizing the likelihood of inbreeding. Within autogamous species, cleistogamous species are those in which pollination occurs before the opening of the flowers while chasmogamous species are those where the pollen is shed after the flower opens. Obviously, allogamy is required for outcrossing but does not ensure that it ...
