How do males produce sperm in the haplodiploid sex-determination system?

Options

  1. ABy meiosis
  2. BBy mitosis
  3. CBy binary fission
  4. DBy fertilization

Correct answer

B. By mitosis

Step-by-step solution

The sex determination in honey bee is based on the number of sets of chromosomes an individual receives. An offspring formed from the union of a sperm and an egg develops as a female (queen or worker), and an unfertilised egg develops as a male (drone) by means of parthenogenesis. This means that the males have half the number of chromosomes than that of a female. The females are diploid having 32 chromosomes and males are haploid, i.e., having 16 chromosomes. This is called as haplodiploid sex-determination system
