Answer :
Answer:
Self incompatibility is a genetic mechanism to prevent self pollination from fertilising the ovules by inhibiting pollen germination or pollen tube growth in the pistil. Due to the inhibition of self fertilisation, self pollination does not lead to seed formation.
Answer: Self-incompatibility is a plant's way of preventing self-fertilization. This means that pollen from the same plant or a similar one can't fertilize its own ovules. In these plants, self-pollination doesn't lead to seed formation because the plant recognizes its own pollen and stops it from growing. This helps the plant avoid wasting energy on seeds that might not grow well.
