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).

Lepidodactylus lugubris measure 8.5–10 cm in length including tail (4–4.4 cm snout-to-vent). [1] [2] L. lugubris is cryptically coloured, typically light to dark tan with dark spots down the length of its back and a brown strip from the ear to the tip of the nose. [1]
Parthenogenesis (/ ˌ p ɑːr θ ɪ n oʊ ˈ dʒ ɛ n ɪ s ɪ s,-θ ɪ n ə-/; [1] [2] from the Greek παρθένος, parthénos, 'virgin' + γένεσις, génesis, 'creation' [3]) is a natural form of asexual reproduction in which the embryo develops directly from an egg without need for fertilization.
The Komodo dragon, which normally reproduces sexually, has also been found able to reproduce asexually by parthenogenesis. [54] A case has been documented of a Komodo dragon reproducing via sexual reproduction after a known parthenogenetic event, [ 55 ] highlighting that these cases of parthenogenesis are reproductive accidents, rather than ...
The Bynoe's gecko is a slender, long-tailed species which may grow to a total length (including tail) of 11–12 cm (4.3–4.7 in). It is covered with small scales which appear to be rough, but are soft to touch. [6] It has slim toes which end with strong claws, but unlike many other gecko species, it does not have expandable toe pads.
Most geckos lay a small clutch of eggs. Some are live-bearing, and a few can reproduce asexually via parthenogenesis. Geckos also have a large diversity of sex-determining mechanisms, including temperature-dependent sex determination and both XX/XY and ZZ/ZW sex chromosomes with multiple transitions among them over evolutionary time. [58]
Gargoyle geckos are primarily nocturnal. [1] [3] [8] They are an arboreal species, making their home in scrub forests. The female lays two eggs per clutch, which hatch 60 to 90 days after they are laid. The female can lay eight or nine clutches per year. On rare occasions, gargoyle geckos can reproduce asexually via parthenogenesis.
The common house gecko (Hemidactylus frenatus) is a gecko native to South and Southeast Asia as well as Near Oceania. It is also known as the Asian house gecko, Pacific house gecko, wall gecko, house lizard, tiktiki, chipkali [3] or moon lizard. These geckos are nocturnal; hiding during the day and foraging for insects at night.
