Read the following statements regarding the chromosomal mechanism of sex determination in certain insects like honeybees: A. The sex of the offspring is determined by the number of sets of chromosomes it receives. B. Gametogenesis in males occurs through equational division. C. A male individual in this system lacks a father and cannot produce sons. D. The females possess 16 chromosomes while the males possess 32 chr

Options

  1. AA, B and C only
  2. BA, C and D only
  3. CB, D and E only
  4. DA, B, D and E only

Correct answer

A. A, B and C only

Step-by-step solution

In the haplodiploid sex determination system found in honeybees, the sex of the offspring is determined by the number of sets of chromosomes it receives. Fertilized eggs develop into diploid females, while unfertilized eggs develop into haploid males (drones) by parthenogenesis. Thus, statement A is correct. Since males are haploid, they produce sperms by mitosis, which is an equational division. Thus, statement B is correct. Because males develop from unfertilized eggs, they do not have a father. Furthermore, sinc
