Question

Why is cross-pollination preferred over self-pollination?

• A. The fruits developed after fertilisation are large.
• B. Variation does not occur.
• C. It increases the chances of variation.
• D. It takes less time for fertilisation.

Answer 1

The correct option is C It increases the chances of variation.

• Cross-pollination is a type of pollination in which pollen grains come from another plant.
• It is preferred because it brings about variation in species.
• Self-pollination does not bring about any variations.
• Variation brings new traits to the plant which may be advantageous to the plant. For example, it helps the new plant to defend against diseases.
