How do unfertilized eggs become drones?
Males, called drones, emerge from unfertilized eggs, and females emerge from fertilized ones and become the workers. So if the queen adds sperm to an egg, it will produce a female; if she withholds sperm, the egg will produce a male. That would appear to give the queen control over the sex of her offspring.
