Question

What are the types of pollination. Which among them is more advantageous? Why?

Answer 1

Pollination is of two types

i) Self pollination

ii) Cross pollination.

Cross-pollination is more advantageous over self-pollination because:-

1. Cross-pollination is beneficial to the race of the plant as it introduces new genes into the lineage as a result of the fertilization between genetically different gametes
2. Cross-pollination improves the resistance of the offsprings to diseases and changes in the environment.
3. The seeds produced as a result of cross-pollination are good in vigour and vitality.
4. If there are any recessive characters in the lineage, they are eliminated as a result of genetic recombination.
5. It is the only way unisexual plants can reproduce.
