Question

What is self incompatibility why does self pollination not lead to seed formation in?

Answer 1

Answer:

Self - incompatibility is a genetic mechanism in angiosperms that prevent self-pollination. The plant which exhibits this phenomenon have the ability to prevent germination of pollen grains and thus prevent the growth of pollen tube on the stigma of the flower. This prevent the fusion of the gametes along the development of the embryo. As a result, no seed formation take place.

Answer 2

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.
