Advantages of sexual reproduction over asexual reproduction are listed below:

  1. Genetic Diversity: Sexual reproduction increases genetic diversity through the combination of genes from two different individuals, leading to the creation of offspring with new traits and adaptations.
  2. Evolution: This increased genetic diversity leads to evolution and helps populations adapt to changing environments.
  3. Protection from disease: The shuffling of genes during sexual reproduction can help protect populations from diseases and parasites by producing offspring with resistance to specific diseases.
  4. Repair of damaged DNA: The process of meiosis involved in sexual reproduction can help repair damaged DNA, preserving genetic integrity.
  5. Increased chances of survival: Sexual reproduction can increase the chances of survival of a species by providing a way to overcome environmental stress, ensuring that some individuals with favorable traits survive to reproduce.

Sexual Reproduction: A type of reproduction in which two individuals of opposite sexes produce offspring through the fusion of their gametes (egg and sperm). This results in offspring that are genetically diverse and have a unique combination of traits from both parents.

Asexual Reproduction: A type of reproduction in which an individual can produce offspring without the involvement of gametes or fertilization. Offspring are identical to the parent and have the same genetic material. Examples include budding, fragmentation, and self-fertilization.
