What are the types of pollination?

Pollination is mainly of two types: self-pollination and cross-pollination.

Self-pollination occurs when pollen grains are transferred from the anther to the stigma of the same flower or another flower on the same plant. This type of pollination usually produces less genetic variation.

Cross-pollination occurs when pollen grains are transferred from the flower of one plant to the flower of another plant of the same species. It often involves agents such as insects, wind, water, or birds and results in greater genetic variation.

Both types of pollination help in fertilization and seed formation, but cross-pollination contributes more to diversity and adaptation in plants.
