Question

What is self-incompatibility ❓​

Answer 1

Answer:

Self-incompatibility is a mechanism that prevents pollen from one flower from fertilizing other flowers of the same plant. Self-incompatibility is often observed in plants belonging to such families as Solanaceae and Rosaceae.

Answer 2

Answer:Self-incompatibility (SI) is a general name for several genetic mechanisms in angiosperms, which prevent self-fertilization and thus encourage outcross and allogamy. It should not be confused with genetically controlled physical or temporal mechanisms that prevent self-pollination, such as heterostyly and sequential hermaphroditism (dichogamy).
