Temperature-dependent sex determination (TSD), where the temperature of the embryo’s environment influences its sex development, is a widespread non-genetic process of sex determination among vertebrates, including reptiles. The sexes of many baby reptiles are determined by the temperature that the eggs experience while being incubated in the nest. What’s more, lizards in the lab have been known to switch to this.
Jun 25, 2007 · A widely held view is that temperature-dependent and genotypic sex determination are mutually exclusive, incompatible mechanisms—in other words, a . Temperature-dependent sex determination (TSD) is a type of environmental sex determination in which the temperatures experienced during embryonic/larval development determine the sex of the offspring. It is only observed in reptiles and teleost fish. TSD differs from the chromosomal sex-determination systems common among vertebrates. It is the most popular and most studied type of.
A sex-determination system is a biological system that determines the development of sexual characteristics in an organism.Most organisms that create their offspring using sexual reproduction have two sexes. Occasionally, there are hermaphrodites in place of one or both sexes. There are also some species that are only one sex due to parthenogenesis, the act of a female reproducing without.
