#self-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.
• Autogamous — Reproducing through autogamy; a botanical and biological term describing an organism, specifically a plant or flower, whose male reproductive structures fertilize its own female reproductive structures. This genetic phenomenon ensures the perpetuation of the species in isolated environments where external pollinators or wind vectors are absent, leading to a high degree of homozygosity within those populations.
• Autogamy — A mode of reproduction characteristic of certain plants and lower organisms, consisting of self-fertilization or self-pollination, a process whereby the fusion of gametes originates from the same individual. This evolutionary biological mechanism guarantees the genetic stability of the species and its perpetuation in isolated or harsh habitats, eliminating structural reliance on external factors such as pollinating insects, wind, or water, although it limits long-term genetic diversity and recombination.
• Self-pollination — A biological reproductive process in spermatophyte plants, characterized by the transfer of pollen grains from the anthers to the stigma of the same flower (autogamy) or of another flower belonging to the same individual (geitonogamy). This endogenous structural mechanism ensures fertilization in the absence of external pollination vectors, but limits the genetic variability of the offspring by increasing homozygosity.
