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 ...
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).
Cnemidophorus is a genus of lizards in the family Teiidae. Species in the genus Cnemidophorus are commonly referred to as whiptail lizards or racerunners. The genus is native to South America, Central America, and the West Indies.
Reproduction occurs through parthenogenesis, with up to four unfertilized eggs being laid in mid summer, and hatching approximately eight weeks later. 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 ...
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.
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).

The rainbow whiptail (Cnemidophorus lemniscatus) is a species of lizard found in Central America, the Caribbean, and northern South America. It has also been introduced in Florida and has established populations there. [1] A rainbow whiptail grows up to approximately 12 inches (30.5 cm). Both sexually reproducing and parthenogenetic populations ...
Desert grassland whiptail lizard females reproduce by obligate parthenogenesis. In obligate parthenogenesis, females only reproduce asexually. [20] One example of this is the desert grassland whiptail lizard, a hybrid of two other species. Typically hybrids are infertile but through parthenogenesis this species has been able to develop stable ...
