Answers
The outbreeding devices in angiosperm plants that encourage cross-pollination are: Dicliny- Flowers are unisexual so that self-pollination is not possible. Prepotency: Pollen grains of another flower germinate more rapidly over the stigma than the pollen grains of the same flower (example apple and grape).
the out breeding devices in angiosperms plants that encourage cross pollination are:
dicliny- flowers are unisexual so that self pollination is not possible ...the plants may be monoecious ,that is ,bearing male and female on different plants (example-mulberry and papaya)
prepotency- pollen grains of another flower germinate more rapidly over the stigma than the pollen grains of the same flower (example-apple and grapes)
self sterility- pollen grains of a flower do not germinate on the stigma of the same flower due to the presence of the similar self sterile genes
