Why does asexual reproduction preserve genetic information while sexual reproduction permits variation?

  1. Asexual reproduction involves fusion of distinct gametes from different parents
  2. Traditional hybridisation ensures the multiplication of only desirable genes
  3. Sexual reproduction provides opportunities for variations and unique combinations of genetic setup, unlike asexual reproduction
  4. Plasmids undergo spontaneous mutations at much higher rates during asexual replication

Correct answer · Option 3

Sexual reproduction provides opportunities for variations and unique combinations of genetic setup, unlike asexual reproduction

Explanation

Sexual reproduction creates unique combinations of genetic setups leading to variations, whereas asexual reproduction preserves identical genetic information.
