Allogamous
Definition
A term describing a plant organism or a species that reproduces exclusively or predominantly through cross-fertilization (allogamy), meaning the union of gametes originating from different individuals. In a structural sense, allogamous plants have developed complex adaptive morphological and physiological mechanisms (such as self-incompatibility, dioecy, or protandry) to prevent self-pollination and ensure high genetic variability.
