1. Incubation temperatures generally range from 26-32 �C ( 79-90 �F ).2. At 26-29 �C incubation temperature the eggs hatched after 61 days. 3. Sex of the hatchlings is not determined by incubation temperature . 4. Incubation temperatures less than 88 �F ( 31 �C ) resulted in all-male clutches.5. Techniques can also be used to minimize DNA degradation, such as cycling the incubation temperature . 6. Some reptiles use incubation temperatures to determine sex. 7. An incubation temperature of 30 �C results in an equal ratio of male to female hatchlings. 8. The sex of red-eared sliders is determined by the incubation temperature during critical phases of the embryos'development. 9. Several species of reptiles have temperature-dependent sex determination, where incubation temperature of eggs determines the sex of the individual. 10. Such incubation temperatures are not allowed in schools, but even at the permitted maximum of 25oC, K-12 still grows well.
