The queen bee is a female bee developed from a fertilized egg. In addition, in the bee world, haploid is male and polyploid is female. That is to say, only the male bee (haploid) is male, and the worker bee (polyploid) and queen bee (polyploid) are female, but the worker bee does not have complete reproductive ability because of the incomplete development of reproductive system. Simply put, only the queen bee can reproduce normally in the bee colony.
