WebSelf-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. In these plants, self-incompatibility is controlled by a single gene locus with a large number of alleles, the S-locus. WebIn angiosperms, self-incompatibility is a phenomenon that prohibits self-fertilization or inbreeding.
