Biology  Self-incompatibility  Self-pollination

selfing A method of seed generation in which pollination is performed manually and the pollen donor and egg donor are from the same plant.


Selfing and Outcrossing
Most flowering plant species reproduce primarily by outcrossing, including the great majority of trees, shrubs, and perennial herbs.

Selfing
Self-fertilization of an organism. Cf. crossing.

Crossing
Fertilization of an organism from an other organism with a different genetic constitution. Cf. Selfing.

Most flowers are hermaphroditic, theoretically enabling fertilization within the same individual (selfing), a breeding system that can lead to detrimental evolutionary consequences [4],[5].

The most common anti-selfing mechanism is self-incompatibility, the ability of a plant to reject its own pollen and that of closely related individuals.

Further, the selfing nature of this plant assists genetic experiments. Also, as an individual plant can produce several thousand seeds, each of the above criteria leads to Arabidopsis thaliana being valued as a genetic model organism.
