The consequences of Temperature dependent sex determination animals to draw in Elizabeth on fitness, or reproductive success, are largely unknown. In this species, high incubation temperature during egg development reverses genotypic males ZZ into phenotypic females; so females can be ZZ or ZW, but males are always ZZ.

A low incubation temperature during the development of this lizard's egg reverses some genotypic females XX into "phenotypic" males—so that they have only functioning male reproductive organs. Bibcode : Sci From Wikipedia, the free encyclopedia. The sexes of many baby reptiles are determined by the temperature that the eggs experience while being incubated in the nest.

  • 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. The temperature experienced in development also has long-term functional outcomes in addition to sex determination.
