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 ...
The asexual, all-female whiptail species Aspidoscelis neomexicanus (center), which reproduces via parthenogenesis, is shown flanked by two sexual species having males, A. inornatus (left) and A. tigris (right), which naturally hybridized to form A. neomexicanus.
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 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 ...
Aspidoscelis mexicanus (W. Peters, 1869) – Mexican whiptail; Aspidoscelis motaguae (Sackett, 1941) – giant whiptail; Aspidoscelis neomexicanus (Lowe & Zweifel, 1952) – New Mexico whiptail; Aspidoscelis neotesselatus (Walker, Cordes & H.L. Taylor, 1997) – Colorado checkered whiptail, triploid checkered whiptail
Asexual reproduction is a type of reproduction that does not involve the fusion of gametes or change in the number of ... The New Mexico whiptail is another example.
Aspidoscelis costatus, also known as the western Mexico whiptail, is a species of whiptail lizard endemic to Mexico, including Guerrero, Morelos, and Puebla in southern Mexico, as well as other Mexican states. Its range spans both temperate and tropical habitats, and even densely populated urban areas.
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.
