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).

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.

Gekko gecko, the Tokay gecko, is a large, common, Southeast Asian gecko known for its aggressive temperament, ... and a few can reproduce asexually via parthenogenesis.
Probably not. Females of species have the ability to reproduce asexually, without sperm from a male. ... crustaceans and lizards reproduce only through parthenogenesis. But in other species it’s ...
On rare occasions, gargoyle geckos can reproduce asexually via parthenogenesis. In their native habitat of southern New Caledonia, they have been known to sustain themselves from a mixed diet. One study [ 3 ] found that they regularly consume a wide taxonomic and ecological variety of arthropods , lizard prey including geckos and skinks, and ...
An interesting aspect to reproduction in these asexual lizards is that mating behaviors are still seen, although the populations are all female. One female plays the role played by the male in closely related species, and mounts the female that is about to lay eggs.
Asexual reproduction is a type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes. The offspring that arise by asexual reproduction from either unicellular or multicellular organisms inherit the full set of genes of their single parent and thus the newly created individual is genetically and ...
The gecko has a “slender” and “relatively robust” body. It’s considered “large,” reaching about 3.1 inches in size. ... a field known as taxonomy, provides a deeper understanding of ...
