Q. Assertion: Self-incompatibility is a genetic mechanism that prevents self-pollen from the same flower or other flowers of the same plant from fertilizing the ovules by inhibiting pollen germination or pollen tube growth in the pistil.
Reason: In gametophytic self-incompatibility, the incompatibility is determined by the genotype of the sporophytic tissue of the plant from which the pollen is derived.
