In honeybees, the male drones develop from unfertilised eggs by the process of:

Answer: parthenogenesis.

  • A normal fertilisation
  • B vegetative budding
  • C simple binary fission
  • D parthenogenesis

Correct answer: D. parthenogenesis

Explanation: Honeybee males are haploid and develop parthenogenetically from unfertilised eggs, while females develop from fertilised, diploid eggs.
