  • Temperature-dependent sex determination and gonadal differentiation in reptiles. Pieau C(1), Dorizzi M, Richard-Mercier N. Author information: (1)Institut Jacques Monod, CNRS, Paris, France. [email protected] by: 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 following review elaborates on gonadal differentiation and growth in reptiles as a function of temperature. Evidence of the early presence of active steroidogenic enzymes and temperature-dependent steroidogenesis in the gonads, and of the involvement of oestrogens in ovary differentiation are presented. Also discussed is the concept of gonadal intersexuality, the possible implications of Author: C. Pieau, M. Dorizzi, N. Richard-Mercier.

  • Temperature-dependent sex determination (TSD) had been observed in all reptilian groups as well as in both XX/XY and ZZ/ZW types of sex determination. The same genes are involved in forming a testis in reptiles with TSD as were described for other vertebrates (see above) although there is some disagreement as to the exact activation sequence. Dec 18,  · Temperature-dependent sex determination (TSD), commonly found among reptiles, is a sex determination mode in which the incubation temperature during a .
