#cross-pollination
- Allocarpic — A term describing a vegetal organism, a fruit, or a reproductive system resulting from cross-fertilization (allogamy), meaning pollination with pollen originating from another flower or from another individual of the same species. In a structural sense, it defines carpic structures or fruits whose genetic development depends strictly on an external pollen contribution, ensuring high genetic variability.
- Allogamous — Relating to plants, flowers, or vegetal species: reproducing via cross-pollination, a biological phenomenon where fertilization is achieved using pollen from another flower belonging to either the same individual or a different individual of the same species. This complex genetic mechanism prevents inbreeding, promotes hereditary variability, and enhances the descendants' adaptability to environmental shifts.
- Allogamy — 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.
- Allosperm — Relating to seeds or plants: a seed formed following cross-pollination (allogamy), bearing an embryo with combined genetic material from two distinct parents; as an adjective, it describes the seminal structure or tissue resulting from exogenous fertilization, characterized by heightened genetic variability and superior adaptability compared to self-fertilized seeds.
- Androdioecious — Pertaining to plants or vegetable species whose populations structurally exhibit two distinct types of individuals: some bearing exclusively male flowers and others bearing only hermaphroditic (bisexual) flowers. This rare reproductive system plays an essential structural role in evolutionary genetics, acting as an intermediate mechanism to promote cross-pollination.
- Andromonoecious — Pertaining to plants or vegetable species whose single individuals structurally bear both hermaphroditic (bisexual) flowers and exclusively male (staminate) flowers on the same stem. This morphological trait represents the adjectival character linked to andromonoecy, playing a major structural role in regulating gene flow and adapting pollination.
- Autoallogamy — A specialized biological term defining the adaptive capacity or phenomenon whereby a plant species structurally combines autogamy (self-pollination) with allogamy (cross-pollination); a flexible reproductive strategy allowing plants to resort to fertilization with own pollen in the absence of external pollination vectors, while maintaining cross-breeding capabilities.
- Self-sterility — A congenital physiological or genetic incompatibility of certain hermaphroditic plants or animals to achieve fertilization through the union of their own gametes (self-fertilization), although these gametes are fully viable and functional when combined with those of other individuals. This structural adaptive mechanism prevents inbreeding and forces cross-pollination, ensuring the genetic variability and biological vigor of the species' offspring.
