Solution:

Queen is the only fertile female in the beehive, having immensely developed ovaries. She lives for several successive years hying about 2000 or more eggs a day. The queen has a remarkable capacity of controlling the fertilization of its eggs. A fertilized egg is laid in a worker or queen cell, while an unfertilized egg in a drone cell, the latter develops parthenogenetically. The queen mates only once in her lifetime. The sperms stored in her spermatheca fertilize her eggs as long as she lives.
