Hello dear good evening I am tanwi and your answer is in down
1) Dicliny: flowers are unisexual so that self pollination is not possible the plant maybe monoesious( wearing both male and female flowers examples maize)
2) Prepotency : pollen grains of another flower germinate more rapidly over the Stigma then the pollen grains of the same flower example Apple, grapes
3) Self sterility : pollen grains of a flower do not germinate on the stigma of the same flower due to presence of similar sterile Gene
example potato .
hope it helps you
Any problem say me
Thank you

➡️. The outbreeding devices are as follows :
❤. Self - incompatibility is the genetic mechanisms that prevents selfie Pollen from fertilizing the ovule by inhibiting Pollen germination a retarding the growth of pollen tube
❤. Certain plant species produce male and female flowers on different plants that is the plants are dioecious this prevents both autogamy and geitonogamy
❤. Pollen release and stigma receptivity are not synchronised, either the answers Major first on the Pistill or gynoecium matures first.
❤. The anthers and stigna of a flower are placed in such a way that the pollen of the flower cannot fall on the stigma of the same flower.
