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).

The eastern bearded dragon (Pogona barbata), also known as common bearded dragon or simply bearded lizard, is an agamid lizard found in wooded parts of Australia. [ 1 ] [ 2 ] [ 3 ] It is one of a group of species known commonly as bearded dragons .
The eggs will hatch approximately 60 to 80 days later, depending on the incubation temperature. In captivity, they can be incubated in a styrofoam fish box, but without a male lizard, the female's eggs will not be fertile. However, a female bearded dragon can retain sperm, and thus produce fertile eggs even after being separated from a male.
The production of female offspring by parthenogenesis is referred to as thelytoky (e.g., aphids) while the production of males by parthenogenesis is referred to as arrhenotoky (e.g., bees). When unfertilized eggs develop into both males and females, the phenomenon is called deuterotoky. [22]
The 'golden retriever' of reptiles. When bearded dragons are happy, they will sit calmly on your lap for hours, comforted by your body heat − because they're cold-blooded, said Thompson, who ...
This group of lizards includes some more popularly known, such as the domesticated bearded dragon, Chinese water dragon, and Uromastyx species. One of the key distinguishing features of the agamids is their teeth, which are borne on the outer rim of their mouths ( acrodonts ), rather than on the inner side of their jaws ( pleurodonts ).
The paternal DNA dissolves or is destroyed before it can fuse with the egg. [1] The egg cell of the organism is able to develop, unfertilized, into an adult using only maternal genetic material. Gynogenesis is often termed "sperm parasitism" in reference to the somewhat pointless role of male gametes. [2]
