 This form of asexual reproduction, called parthenogenesis, occurs in several species of gecko, and is particularly widespread in the teiids (especially "Aspidocelis") and lacertids ("Lacerta").In captivity, Komodo dragons (Varanidae) have reproduced by parthenogenesis.Parthenogenetic species are suspected to occur among chameleons, agamids, xantusiids, and typhlopids.
