Arrhenotoky
Definition
A particular form of arrhenotokous parthenogenesis in which unfertilized eggs develop structurally and exclusively into male individuals (haploid males). This biological mechanism is characteristic of many social insect species belonging to the Hymenoptera order (bees, wasps, ants), ensuring the production of drones within the colony.
