प्रश्न
What are the advantages of sexual reproduction over asexual reproduction?
उत्तर १
Advantages of sexual reproduction:
- The fusion of male and female gametes from male and female parents occurs during sexual reproduction. The offspring have a diversity of personalities since the merging gametes originate from two separate and sexually diverse individuals.
- The newly formed individual has characteristics of both parents.
- Variations are more viable in the sexual mode than in the asexual one. This is because in asexual reproduction, DNA has to function inside the inherited cellular apparatus.
उत्तर २
- Sexual reproduction plays an important role in the origin of new species with different characteristics, which is not possible in the case of asexual reproduction.
- Sexual reproduction produces genetic variations, which produce diversity of characters, whereas it is not possible in asexual reproduction.
