| Characteristic | Self-Pollination | Cross-Pollination |
|---|---|---|
| Process | Pollen from a flower’s anther lands on the stigma of the same flower or another flower on the same plant. | Pollen is transferred from the anther of a flower on one plant to the stigma of a flower on a different plant of the same species. |
| Genetic Variation | Results in minimal or no genetic variation, leading to less genetic diversity within the plant. | Leads to high genetic variation, promoting diversity and adaptation in the plant. |
| Pollinators | Does not usually require pollinators, as the pollen transfer happens within the same plant. | Pollinators, such as insects, birds, or wind, are often required to transfer the pollen between plants. |
| Examples | Common self-pollinating plants include peas, wheat, and peanuts. | Apples, daffodils, and maize are examples of cross-pollinating plants. |
