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]
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]
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.
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.
Females of species have the ability to reproduce asexually, without sperm from a male. ... Some plants and insects can do it, as well as some amphibians, ... crustaceans and lizards reproduce only ...
These lizards live in the dry and sometimes harsh climate of the southwestern United States and northern Mexico. All these asexual species appear to have arisen through the hybridization of two or three of the sexual species in the genus leading to polyploid individuals. The mechanism by which the mixing of chromosomes from two or three species ...
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 gecko has a “slender” and “relatively robust” body. It’s considered “large,” reaching about 3.1 inches in size. A photo shows the forest dwarf gecko. It has a tannish coloring ...
