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.
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.

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).

Females of species have the ability to reproduce asexually, without sperm from a male. The process is called parthenogenesis, from the Greek words for “virgin” and “birth.”
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 ...
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]
Obligate parthenogenesis is the process in which organisms exclusively reproduce through asexual means. [39] Many species have transitioned to obligate parthenogenesis over evolutionary time. Well documented transitions to obligate parthenogenesis have been found in numerous metazoan taxa, albeit through highly diverse mechanisms.
