Darevskia unisexualis

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

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