Autogamous
Definition
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.
