Abstract
The discovery of multiple unisexual lizard populations started in the early 1900s and stirred up many scientific questions. Later, numerous usually sexually reproducing vertebrates were observed to produce successful parthenogenetic offspring in captive conditions. For many years scientists have tried to solve the long standing paradox of the maintenance of obligate sexual reproduction in the animal kingdom despite its high reproductive costs. Reptiles are a model class for this study thanks to their diverse use of reproductive strategies. This essay focuses on two main questions, 1) Which parthenogenetic mechanisms exist and when do they occur? 2) What are the costs and benefits of reproducing through facultative versus obligate parthenogenesis and hence which environmental conditions promote these reproductive strategies?
