In polyploid obligate parthenogens, like the whiptail lizard, all the offspring are female. [27] In many hymenopteran insects such as honeybees, female eggs are produced sexually, using sperm from a drone father, while the production of further drones (males) depends on the queen (and occasionally workers) producing unfertilized eggs.

The western whiptail's chromosomes show that it is polyploid. It is also a bisexual species, containing both males and females, unlike other species of Aspidoscelis which are all-female. Usually in the northern end of its range, mating occurs in the first half of June, and females begin to lay eggs in late June.
