How Does Temperature Affect Sex In Reptiles?

💡 The Answer

• In many reptiles, sex is determined by incubation temperature rather than genetics. This process is called temperature-dependent sex determination.
• Higher or lower temperatures can influence whether embryos develop as male or female. Each species has its own threshold range.
• Bearded dragons are unusual because both genetics and temperature play roles. High temperatures can override genetic sex.
• A genetically male bearded dragon can become a functional female when incubated above 32°C. This shows a unique biological flexibility.
