Meaning and Definition
A form of parthenogenesis in which unfertilized eggs develop into males.
A reproductive system found in some insects (especially Hymenoptera like bees, ants, and wasps) and other arthropods where males are produced from unfertilized haploid eggs, while females are produced from fertilized diploid eggs. This determines the sex of offspring based on fertilization.

Arrhenotoky produces males from unfertilized eggs, while thelytoky produces females from unfertilized eggs.
It is a mixed system. The production of males is asexual (parthenogenetic), but females are produced sexually from fertilized eggs. The population requires both processes.
It is central to haplodiploid sex-determination systems, which influence social structure, kin selection, and the evolution of eusociality in insects like ants and bees.
