Obligate parthenogenesis as a reproductive system has evolved multiple times in the family Gekkonidae. It has been shown that oocytes are able to undergo meiosis in three different obligate parthenogenetic complexes of geckos. An extra premeiotic endoreplication of chromosomes is essential for obligate parthenogenesis in these geckos. Appropriate segregation during meiosis to form viable progeny is facilitated by the formation of bivalents made from copies of identical chromosomes.
