Web4 Jan 2024 · However, parthenogenetic species are often termed as ‘dead-ends’, since they produce clones, which do not have any new trait combinations. Because all the offspring are clones and are incapable of adapting to changing environments, they succumb faster to disease, which can ultimately threaten or reduce their populations in drastic ways.

The production of female offspring by parthenogenesis is referred to as thelytoky (e.g., aphids) while the production of males by parthenogenesis is referred to as arrhenotoky (e.g., bees). When unfertilized eggs develop into both males and females, the phenomenon is called deuterotoky.
