The difference between self-pollination and cross pollination are:
- Pollination of the stigma by the pollen grains of the same flower.
- It does not provide opportunity for genetic variability.
- Examples: pea, wheat, rice.
- Pollination of the stigma by the pollen grains of another flower of a different plant.
- It provides opportunity for genetic recombination and greater variability.
- Examples: maize, Mulberry.
