Q71 / 270 · NDA 2023 (Phase 1) · General Ability

One advantage of sexual reproduction over asexual reproduction is that it helps species to survive over long evolutionary time. This is because sexual reproduction produces :

  • A
    more offspring in each reproductive cycle.
  • B
    robust and healthy offspring.
  • C
    genetically similar offspring.
  • Correct answer
    D
    more variation in offspring.

Solution

Sexual reproduction involves two parents, whereas asexual reproduction involves only one parent. The offspring resulting from sexual reproduction therefore have characteristics from both the parents and therefore, will be different from each parent. This will bring variations in the population. Variations are important for the survival of species over time.

Hence, the correct answer is option: 'D'.
