The results, which found evidence of TSD in four out of five species, confirmed that some vertebrate species exhibit TSD. Temperature-Dependent Sex Determination in Reptiles The sex of a reptile embryo partly results from the production of sex hormones during development, and one such process to produce those hormones depends on temperature of the embryo's environment.
Temperature-dependent aromatase activity is also seen in diamondback terrapins, and its inhibition masculinizes their gonads Jeyasuria et al.
Assessment of RainDrop BS-seq as a method for large-scale, targeted bisulfite sequencing. Heloderma suspectum Gila Monster. Hence, it is worth mentioning that an environmental factor such as temperature or population density may be connected to sex through epigenetic mechanisms.
