Answer 1

This pattern of expression in reptiles can best be explained by the influence of temperature on sex determination. In many reptiles, the sex of the offspring is determined by the temperature of the eggs during a critical period of development. Eggs that are kept at warmer temperatures are more likely to develop into females, while eggs that are kept at cooler temperatures are more likely to develop into males. This is known as temperature-dependent sex determination, and it is thought to be an adaptation that allows reptiles to control the sex ratio of their offspring in response to environmental conditions.

Answer 2

TSD ↓

Step-by-step explanation:

The pattern of sex determination in reptiles that is influenced by the temperature at which the eggs are incubated is known as temperature-dependent sex determination (TSD). This phenomenon is thought to be controlled by hormones and other factors that are sensitive to temperature. For example, if a particular hormone (such as estrogen) is present at higher levels during incubation, it may promote the development of female characteristics in the developing embryo. On the other hand, if this hormone is present at lower levels, it may promote the development of male characteristics. The exact mechanisms underlying TSD are not fully understood, but it is clear that temperature plays a crucial role in determining the sex of these animals.
