प्रश्न
Write the importance of sexual reproduction in nature.
Reproduction is one of the most important characteristics of living beings. Give three reasons in support of the statement.
उत्तर १
Importance of sexual reproduction:
Sexual reproduction involves fusion of male and female gametes coming from both the parents. The fusion of these gametes results in genetic variations in the offsprings. This way sexual reproduction promotes diversity of characters in offsprings by providing genetic variations. These genetic variations, thus, lead to evolution of species as well as allow the organisms to become better adapted in the changing environment.
उत्तर २
Reproduction is an energy consuming process which is not essential for the survival of an individual. But it is a highly important characteristic of all the living beings, because of the following reasons:
1. Reproduction helps in increasing the number of members of a population.
2. By replacing the dead members with the new ones, it minimizes the risk of extinction of a species.
3. It brings about variations in species, thus, leading to their evolution.
