Self-pollination

Biology  Selfing  Self-splicing

Self-pollination is where the pollen is transferred to the stigmas of the same flower or the stigma of another flower on the same plant. Self-pollination is obviously more reliable, particularly if the nearest plant is not very close.



The transfer of pollen from anther to stigma in the same flower or to another flower of the same plant, leading to self-fertilization.

Self-pollination. Pollen of one plant is transferred to the female part of the same plant or another plant with the same genetic makeup.

- The process by which the male gametes of a plant fertilize the eggs of the same plant.
Sporangium - The part of a plant where spores are produced.
Spore - Haploid cell from which a gametophyte is produced.

Transfer of pollen (pollination) from the anther of a flower to the stigma of the same flower or sometimes to that of a genetically identical flower (as of the same plant or clone).

Transfer of pollen from stamen to stigma within the same plant.
self-pollinating plant A plant that has its own pollen fall on its own stigma.

Pollination can be cross-pollination with a pollinator and an external pollenizer, self-pollenization with a pollinator, or self-pollination without any pollinator: ...

Mendel's experimental organism was a common garden pea (Pisum sativum), which has a flower that lends itself to . The male parts of the flower are termed the anthers. They produce pollen, which contains the male gametes (sperm).

Switching from Cross-Pollination to Self-Pollination
A substantial minority of angiosperms have abandoned cross-pollination for self-pollination. For example, while its wild relatives continue to be cross-pollinated, the domestic tomato is not.

During , the gametes of these two classes unite randomly.
This produces four equally likely combinations of sperm and ovum.
A Punnett square predicts the results of a genetic cross between individuals of known genotype.

Seed produced through self-pollination ("selfed" seed) is often inferior in growth, survival, and fecundity to seed produced through outcross pollination ("outcrossed" seed).

/OUT-cross/ (1) mating in which the male and female gametes are derived from different individuals; used in opposition to self-fertilization; (2) the pollination of a stigma with pollen from another plant (used in opposition to ); ...

to the stigma of the same flower or sometimes to that of a genetically identical flower (as of the same plant or clone). Ability of many plant species to naturally and successfully fertilize within one individual.
Also called self-pollination.

It is a plant model system of choice because of the additional advantages of short generation time (about five weeks), high seed production (up to 40,000 seeds per plant) and natural ...
