In which animal do haploid cells divide mitotically to produce...

Male honeybees (drones) are haploid organisms that develop parthenogenetically from unfertilized eggs.

Since their body cells are already haploid, they cannot undergo meiosis to produce gametes. Instead, they produce sperm cells through mitotic division.

Earthworms, frogs, and grasshoppers are diploid organisms and produce gametes through meiosis.

Answer: Male honeybees
