WebJan 3, 2024 · Some species of angiosperms can avoid self-fertilization through self-incompatibility (Bateman 1952). In plants with self-incompatibility, the process by which the sperm meets the egg is interrupted at some stage if pollen grains have a genotype that is the same as the parent (e.g. Schopfer et al. 1999). This prevents selfing – and also ... WebIncompatibility in angiosperms is distinguished from other outbreeding mechanisms, but in fungi the distinction between separation of the sexes (dioecy) and incompatibility is a fine one. An incompatibility system is operating when all mating groups have the attributes and potentialities of both sexes. The most satisfactory method of ...
