Explanation

• 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 unfertilized egg develops as a male (drone) by means of parthenogenesis.
The females are diploid having 32 chromosomes and males are haploid, i.e. having 16 chromosomes.
• This is called as haplo-diploid sex determination system and has special characteristic features such as the males produce sperms by mitosis they do not have father and thus cannot have sons, but have a grandfather and can have grandsons.
