Several species of whiptail lizards are entirely female and no males are known. [3] These all-female species reproduce by obligate parthenogenesis (obligate, because the lizards do not involve males and cannot reproduce sexually). Like all squamate obligate parthenogenetic lineages, parthenogenetic teiids are hybrids.
The desert grassland whiptail lizard (Aspidoscelis uniparens) is an all-female species of reptiles in North America. It was formerly placed in the genus Cnemidophorus. A common predator of the whiptail lizard is the leopard lizard that preys on A. uniparens by using ambush and stalk hunting tactics. [2] [3] [4] These reptiles reproduce by ...
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 New Mexico whiptail lizard is a crossbreed of a western whiptail, which lives in the desert, and the little striped whiptail, which favors grasslands. The whiptail engages in mating behavior with other females of its own species, giving rise to the nickname "lesbian lizards".
Occasionally, a mating between a female of one species and a male of another produces a parthenogen, a female that is able to produce viable eggs that are genetically identical to her own cells. The lizards that hatch from these eggs are thus also parthenogens that can again produce identical eggs, resulting in an asexual, clonal population.
Two new types of lizards hatched this year at Columbus Zoo and Aquarium. In the zoo's reptile building, Desert Grassland Whiptail lizards hatched on Jan. 20, the first hatchlings of the year.
Parthenogenesis is a mode of asexual reproduction in which offspring are produced by females without the genetic contribution of a male. Among all the sexual vertebrates, the only examples of true parthenogenesis, in which all-female populations reproduce without the involvement of males, are found in squamate reptiles (snakes and lizards).

Cnemidophorus arubensis, commonly known as the Aruba whiptail or cododo, is a species of whiptail lizard in the genus Cnemidophorus. The female and young lizards are known as Lagadishi (English: Lizard), while the mature males are called Blòblò (English: Blue-blue). [ 1 ]
