How does the chromosome number of males compare to females in honey bees?

Options

  1. AMales have twice as many chromosomes as females
  2. BMales have half the number of chromosomes as females
  3. CMales and females have the same number of chromosomes
  4. DMales have more chromosomes than females

Correct answer

B. Males have half the number of chromosomes as females

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
