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). [1]
Some documented species, specifically salamanders and geckos, that rely on obligate parthenogenesis as their major method of reproduction. As such, there are over 80 species of unisex reptiles (mostly lizards but including a single snake species), amphibians and fishes in nature for which males are no longer a part of the reproductive process.

Pacific geckos mate between Match and May, and give birth to one or two young between February and March. Young geckos take between three and four years to become sexually mature. [ 9 ]
"Fewer than a dozen of the 6455 species of frogs in the world are known to have internal fertilization, and of these, all but the new species either deposit fertilized eggs or give birth to froglets."
Mediterranean house geckos reach sexual maturity within four months to a year. Male house geckos produce clicking sounds to attract a mate, with the females responding in their own squeaks. They also display copulatory biting, with stronger bites resulting in higher fertilization success. Fertilization is internal.
Like other New Zealand geckos, harlequin geckos breed and develop very slowly, with a female giving birth to only one offspring every two or three years. Each generation, which takes about 20 years to mature, appears to have about 30% fewer individuals than the previous generation.
Karamoja dwarf geckos are considered “large,” reaching about 3 inches in size. They have “slender” bodies, “rounded” snouts and several “chevrons” on their throats. These geckos ...
In the U.S., geckos are common in Texas, Florida, California, and other southern states. Why Does the Gecko’s Skin Repel Water? The benefit of hydrophobic skin is that it is self-cleaning.
