How is sex determined in honey bees?

Options

  1. ABy the presence of a Y-chromosome
  2. BBy the number of sets of chromosomes an individual receives
  3. CBy the presence of specific environmental factors
  4. DBy the sex chromosomes alone

Correct answer

B. By the number of sets of chromosomes an individual receives

Step-by-step solution

The sex determination in honey 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 sex-determination system and has special cha
