In asexual reproduction, parthenogenesis occurs when an egg grows into a full-fledged
individual without being fertilized. Depending on the process and the species, the offspring can be
either haploid or diploid. Invertebrates like water fleas, rotifers, aphids, stick insects, some ants,
wasps, and bees engage in parthenogenesis. Bees produce haploid males through parthenogenesis
(drones). When eggs are fertilized, diploid females emerge; however, when fertilized eggs are fed a
special diet (known as royal jelly), a queen emerges.
A few vertebrate species, including some amphibians, fish, and reptiles, also reproduce
through parthenogenesis. Parthenogenesis has been seen in animal species that were separated by sex
in terrestrial or marine zoos, despite the fact that it is more typical in plants. When separated from
males, four female animals—two Komodo dragons, a hammerhead shark, a blacktop shark—all
produced parthenogenic offspring
