WebA second type, gametophytic self-incompatibility, involves the inability of the gametes from the same parent plant to fuse and form a zygote or, if the zygote forms, then it fails to develop. These systems force outcrossing and maintain a wide genetic diversity. WebThe incompatibility is due to genotype of sporophytic or stigmatic tissues, e.g., Asteraceae, Brassicaceae. The genetic basis of self compatibility was proposed by East and Mangelsdorf (1925) in the form of multiallelic single gene, S-gene. It contains over 30 alleles in Brassica oleracea. kyogle uniting church
