Temperature-Dependent Sex Determination in Gekko japonicus (Gekkonidae, Reptilia). (temperature-dependent sex determination/Gekko japonicus/sex differentiation/Reptilia)

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 ...

Temperature-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...
