Question

Compare and contrast the importance of cross-pollination and self-pollination.

Answer 1

Cross-pollination:

1. Cross-pollination produces seeds that are vigorous and active.
2. Plants are becoming more adaptable.
3. It boosts offspring's resistance to illnesses and environmental changes.
4. Unisexual plants can only reproduce in this manner.

Self-pollination:

Pollen transfers from a flower's anther to the stigma of the same flower or occasionally to a genetically identical flower.

Importance of cross-pollination and self-pollination:

1. Cross-pollination produces healthier seeds and fruits.
2. Cross-pollination in multiple generations can be used to create new kinds.
3. As a result, it plays a part in the evolution of species.
4. Cross-pollination produces offspring that are more environmentally adapted.
5. Because there is no genetic recombination, repeated self-pollination through generations leads to inferior progeny.
6. Improved progeny results due to cross-pollination.
