Question

What is self Incompatibility.

Answer 1

Self-incompatibility is a widespread mechanism in flowering plants that prevents inbreeding and promotes outcrossing. The self-incompatibility response is genetically controlled by one or more multi-allelic loci, and relies on a series of complex cellular interactions between the self-incompatible pollen and pistil.

Answer 2

Hey mate , here is your answer

Self incompatibility (S.I) is a general name for several genetic mechanisms in angiosperms, which prevents self- fertilisation and thus encourages outcross and allogamy
