Temperature-dependent sex determination
Reptiles posses two main mechanisms of sex determination. In some species the sex of the individual is determined at conception by sex factors contained in sex chromosomes (termed genotypic sex determination or GSD). However, in other species sex is determined after conception by the environmental temperature during incubation and cannot be predicted by zygotic genotype (Bull, 1983; Valenzuela ...
متن کاملNest Temperature Is Not Related to Egg Size in a Turtle with Temperature-Dependent Sex Determination
A recent hypothesis posits that temperature-dependent sex determination (TSD) in reptiles may be maintained if females can assess thermal conditions and lay eggs accordingly to produce the sex benefiting most from maternal investment. Specifically, females should lay large eggs in environments likely to produce the sex benefiting most from larger egg size. This relationship has been demonstrate...
متن کاملTemperature-Dependent Sex Determination in Reptiles
The sex of a reptile [6] embryo partly results from the production of sex hormones [7] during development, and one such process to produce those hormones [8] depends on temperature of the embryo's environment. The production of sex hormones [7] can result solely from genetics or from genetics in combination with the influence of environmental factors. In genotypic sex determination [9], also ca...
