Allogamy
Definition
A biological phenomenon and mode of plant reproduction characterized by cross-pollination; the process whereby the ovules of a flower are fertilized by pollen originating from another flower of the same specimen or from a different individual of the same species. Allogamy represents the primary evolutionary engine in the plant kingdom, ensuring a constant flow of new genes and heightened disease resistance.
