Magnified view of a male and female fig wasp Pleistodontes imperialis next to the "eye" of an ordinary sewing needle. Mortensen , University of Florida. Life is hard, but it's better when you're not alone. This is important, as male development is only induced in the absence of fem activity and as constant activity of the positive feedback loop would lock eggs into the female determined state. Later on and throughout development this inductive signal is maintained via a positive feedback loop of the feminizer fem gene, in which the Fem protein mediates its own synthesis. Queens and worker bees are female and are made from fertilised eggs, so they receive genes from both the queen and a drone from another hive Workers do not sexually mature and so cannot breed but have important roles in maintaining and building the hive, feeding larvae and foraging for pollen Queens begin life similar to workers but, while workers switch from being fed a diet of royal jelly to a mixture of nectar and pollen, queens continue to be exclusively fed the protein- and sugar-dense jelly and so become sexually mature and much larger than other bees Drones are hatched from unfertilised eggs and so only receive genes from the queen.
