Question
State one reason why cross-pollination is preferred over self-pollination.
✓
Answer
Cross pollination is preferred over self pollination for the following reasons:
- Cross pollination produces variety in species by recombination of genes whereas self pollination maintains the purity of plants and do not contribute to variety.
- Genetic recombination in cross pollination produces healthier progenies generation to generation whereas in self pollination progenies become weaker and weaker and more prone to diseases.
