(Darevsky, 1966)

Darevskia unisexualis is a lizard species in the genus Darevskia . It is found in Armenia, Georgia, and Turkey. [2]

D. unisexualis is capable of parthenogenetic reproduction by oogenesis in female only lineages [3] . During the prophase I stage of meiosis homeologous chromosomes (originally inherited from two different parental species) undergo synapsis [3] . A protein MLH1 employed in DNA mismatch repair also appears to be involved in this meiotic process [3] .

Darevskia is a genus of wall lizards of the family Lacertidae. Member species are native to the Caucasus, Iran and Turkey, living in forest and grassy habitats with numerous rock outcrops. Among rock lizards, seven parthenogenetic species are known.

The desert grassland whiptail lizard is an all-female species of reptiles in North America. It was formerly placed in the genus Cnemidophorus. A common predator of the whiptail lizard is the leopard lizard that preys on A. uniparens by using ambush and stalk hunting tactics. These reptiles reproduce by parthenogenesis. In this process, eggs undergo a chromosome doubling after meiosis, developing into lizards without being fertilized. However, ovulation is enhanced by female-female courtship and mating (pseudo-copulation) rituals that resemble the behavior of closely related species that reproduce sexually.

<span class="mw-page-title-main">Parthenogenesis</span> Asexual reproduction without fertilization

Parthenogenesis is a natural form of asexual reproduction in which growth and development of an embryo occur directly from an egg, without need for fertilisation. In animals, parthenogenesis means development of an embryo from an unfertilized egg cell. In plants, parthenogenesis is a component process of apomixis. In algae, parthenogenesis can mean the development of an embryo from either an individual sperm or an individual egg.

Darevskia alpina is a species of lizard in the family Lacertidae. It is found in the Greater Caucasus in Georgia and Russia.

Darevskia chlorogaster, the greenbelly lizard, is a lizard species in the genus Darevskia. It is found in Azerbaijan and Iran.

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. There are about 50 species of lizard and 1 species of snake that reproduce solely through parthenogenesis. It is unknown how many sexually reproducing species are also capable of parthenogenesis in the absence of males, but recent research has revealed that this ability is widespread among squamates.
