Self incompatibility system

A self-incompatibility system is the term used to describe mechanisms of living beings whose use is to actively prevent the formation of offspring from self-fertilization .

The formation of separate sexes in different individuals ( dioceses ) is one way of implementing this. We speak of genders when two differently shaped sex cells are formed and these then form a fertilized egg cell . For example, two egg cells cannot fertilize each other. However, self-incompatibility systems in the strict sense of the word are mechanisms, regardless of gender, to prevent certain reproductive combinations.

Self-incompatibility systems exist both in plants (see self-incompatibility in plants ), fungi (see cross-breeding type ) and in animals.
