The primary mating systems in plants are [[outcrossing]] (cross-fertilisation), [[autogamy]] (self-fertilisation) and [[apomixis]] (asexual reproduction without fertilization, but only when arising by modification of sexual function). [[Mixed mating systems]], in which plants use two or even all three mating systems, are not uncommon.<ref name="Brown 1989">{{cite book | author = Brown, A. H.

A number of models have been used to describe the parameters of plant mating systems. The basic model is the [[mixed mating model]], which is based on the assumption that every fertilisation is either self-fertilisation or completely random cross-fertilisation. More complex models relax this assumption; for example, the [[effective selfing model]] recognises that mating may be more common between pairs of closely related plants than between pairs of distantly related plants.<ref name="Brown 1989"/>
