Answer:
One advantage of sexual reproduction over asexual reproduction is , sexual reproduction provides genetic diversity.
Explanation:
- Asexual reproduction is the type of reproduction which does not involve the formation or fusion of Gametes.
- Since no fusion of gametes takes place, traits do not combine and no genetic variation results.
- Sexual reproduction involves the production and fusion of male and female gamete.
- Since the participating gametes come from different individuals, their traits combine are present in the offspring.
- Sexual reproduction causes genetic variation and development of new characters in the offsprings.
- This leads tp genetic diversity in the population.
