Here, the female has two different sex chromosomes called a Z and W while the male has two Z chromosomes. Can sex chromosomes and TSD co-exist in the same species? Mol Ecol Resour Sometimes it's quite easy to tell, especially if your gecko is a bit older.
The brown circle are called 'spurs'. I have never found this to be a consistent method to determine the sex of the gecko. This can happen sometimes as early as 6 months old but generally doesn't show up until around a year or so old. Independent origins and rapid transitions. At high incubation temperatures, all of the hatchlings are females. But how are the sexes produced? You may have seen one if you have been to the jeweler or a coin collector. You can wait and take it to a reptile show, but you want to know now! If you don't see any pores and the gecko is over 15 grams, you likely have a female.

Create an account Your crested geckos are now about months old and you naturally want to know their sex- do you have a male or a female. Most gecko species reproduce sexually and both a male and female are required for successful breeding. Mourning Geckos Lepidodactylus lugubris are an all female species that clone themselves to reproduce, a process known as parthenogenesis. However, genetic tests indicate that only half of those high temperature females have W chromosomes. However, these loupes are usually expensive. All that is needed to identify TSD are several reliable incubators and the ability to produce and raise a large number of geckos until they are old enough to be confidently sexed. The incredible diversity of gecko sex-determining systems makes them an ideal group to study how sex-determining systems evolve over time. Sometimes, well fed females will also show a bulge however. Sex reversal triggers the rapid transition from genetic to temperature-dependent sex. They form in a straight line between the legs. Of course you can take him or her to a pet store but will they really know the difference some are very knowledgeable but others not so much. We sell a nice one that has both 30x and 60x magnifications and LED lights to help you see what you're trying to see. Karyotyping cannot identify these sex chromosomes. In species with sex chromosomes the sex of the embryo is determined at fertilization depending on its chromosome complement. This is different from facultative parthenogenesis, which has been documented in some species of sexually reproducing snakes and lizards and occurs when a female has fertile offspring without mating.
