  • TSD is very common in reptiles, where the ambient temperature during sensitive periods of early development irreversibly determines whether an individual will be male or female. The number of males and females in a population is the sex ratio, a key demographic parameter crucial for population viability.

  • Temperature-dependent sex determination 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 environmental sex determination. Some other conditions, e.g. density. All reptiles (or at least reptile species that have no sex chromosomes) display temperature-dependent sex determination (TSD), rather than genetic sex determination. TSD is observed in many fish, all crocodilians, many turtles, and lizards. Sex in reptiles is determined by the temperature of the egg halfway through embryogenesis (Crews, ).
