What is unusual about the reproduction of the desert grassland whiptail lizard?

The desert grassland whiptail lizard exhibits a unique form of reproduction known as parthenogenesis, where females can reproduce without mating with males. This asexual reproduction results in offspring that are genetic clones of the mother. Additionally, these lizards can also engage in sexual reproduction with males, but the ability to reproduce independently is unusual among reptiles. This adaptation allows them to thrive in environments where males may be scarce.
