Evolutionary change requires adaptive traits, which are heritable traits that enhance an individual’s fitness?

Heritable traits that enhance fitness are traits that boost their chances of survival.

Explanation:

Darwinian fitness, the survival of the fittest, says essentially animals with the most beneficial traits tend to out-compete others without the trait. A lot of factors influence how well they compete, but some heritable traits for animals include camouflage (color), limb adaptation, and speed.

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
