The transfer of pollen grains from the anthers of a flower to the stigma of the same flower is known as Self-pollination.
Self-pollination limits the variety of progeny and may depress plant vigour. Both hermaphrodite and monoecious species have the potential for self-pollination leading to self-fertilization unless there is a mechanism to avoid it. 80% of all flowering plants are hermaphroditic, meaning they contain both sexes in the same flower.
