White-bellied lizard

The White-bellied lizard, scientifically known as *Darevskia unisexualis*, is a species of lizard found in Armenia, Georgia, and Turkey. This species is notable for its ability to reproduce asexually through parthenogenesis, where females produce offspring without fertilization. It belongs to the genus *Darevskia* and is part of a larger group of lizards known for their unique reproductive strategies.

Key Facts

  • Found in Armenia, Georgia, and Turkey.
  • Capable of parthenogenetic reproduction.
  • Reproduction occurs through oogenesis in female-only lineages.
  • Involves synapsis of homeologous chromosomes during meiosis.
  • The protein MLH1 plays a role in its meiotic process.

About White-bellied lizard

White-bellied Lizard (Darevskia unisexualis)

The White-bellied lizard, scientifically designated as Darevskia unisexualis, is a notable species within the Darevskia genus. Its natural range encompasses parts of Armenia, Georgia, and Turkey. This lizard is particularly distinguished by its remarkable capacity for parthenogenetic reproduction, a form of asexual reproduction occurring exclusively in female lineages through oogenesis.

Reproductive Biology

The reproductive mechanism of Darevskia unisexualis involves a fascinating meiotic process. During the prophase I stage of meiosis, homeologous chromosomes—those originating from different parental species—engage in synapsis. Further contributing to this unique biological function, the protein MLH1, typically involved in DNA mismatch repair, also plays a role in the meiotic events of this species.

Frequently Asked Questions

What is the scientific name of the White-bellied lizard?

The scientific name of the White-bellied lizard is *Darevskia unisexualis*. This binomial nomenclature identifies it within the genus *Darevskia*.

Where can the White-bellied lizard be found?

The White-bellied lizard is naturally found in the countries of Armenia, Georgia, and Turkey. These regions form its primary geographic distribution.

How does the White-bellied lizard reproduce?

The White-bellied lizard is capable of parthenogenetic reproduction. This means that females can produce offspring through oogenesis without the need for fertilization by a male.

What is unique about its reproductive process?

During meiosis, homeologous chromosomes, which were originally inherited from two different parental species, undergo synapsis. The protein MLH1, involved in DNA mismatch repair, also appears to participate in this specialized meiotic process.
