What is self-incompatibility? Why does self-pollination not lead to seed formation in self-incompatible species?
Self-incompatibility is a genetic mechanism in angiosperms that forestalls self-pollination. It develops genetic incompatibility among people of the identical species or among people of various species. The flowers which show off this phenomenon have the capacity to save you germination of pollen grains and thus, save you the increase of the pollen tube at the stigma of the flower. This prevents the fusion of the gametes in conjunction with the improvement of the embryo. As a result, no seed formation takes place.
