Male gamete IV. Haploid cell formed by mitosis Choose the correct answer from the options given below:

Options

  1. AA-I, B-III, C-II, D-IV
  2. BA-III, B-II, C-I, D-IV
  3. CA-III, B-I, C-II, D-IV
  4. DA-II, B-I, C-IV, D-III

Correct answer

C. A-III, B-I, C-II, D-IV

Step-by-step solution

In honeybees, sex determination is based on the haplodiploid system. The queen is a fertile female that develops from a fertilized egg, making her diploid and fertile (A-III). The worker bees are also females developed from fertilized eggs, but their diet renders them sterile, making them diploid and sterile (B-I). The drone is a male that develops from an unfertilized egg via parthenogenesis, making him haploid and fertile (C-II). Since the drone is already haploid, it produces male gametes (sperms) through mitosi
