Question
What is self-incompatibility? Why does self- pollination not lead to seed formation in self- incompatible species?

Answer

→ Self-incompatibility refers to a genetically controlled mechanism that prevents self- pollination and promote cross-pollination in flowers.
→ Self-pollination cannot lead to the formation of seeds in a self-incompatible species. This happens because the pollens are unable to fertilize the ovules that would develop into an embryo and hence form seeds.
