Step-by-step solution
Queen is the only fertile female in beehive, having immensely developed ovaries. She lives for several successive years laying about 2000 or more eggs a day. The queen has a remarkable capacity of controlling the fertilisation of its eggs. A fertilised egg is laid in a worker or queen cell, while an unfertilised egg in a drone cell, the latter develops parthenogenetically. The queen mates only once in her life time. The sperms stored in her spermatheca fertilise her eggs as long as she lives.
