Question
Environmental sex determination, as described for some reptiles in the chapter, differs fundamentally from human sex determination because it depends on
genetic inheritance from the father, exactly like humans
external environmental conditions (like temperature) rather than inherited chromosomes
the mother's blood type
the number of eggs laid
Detailed Explanation
Unlike the largely genetic determination in humans, some reptiles' sex is set by an external environmental factor (incubation temperature), not inherited chromosomes.
