    Solution

    Self-incompatibility is a mechanism in plants that prevents self-pollination or mating between closely related individuals. It promotes cross-pollination by inhibiting the fertilization of ovules with pollen from the same plant or a closely related plant. This mechanism ensures genetic diversity and reduces the likelihood of inbreeding.
