Many oviparous reptiles exhibit temperature-dependent sex determination (TSD); i.e., the temperature at which the egg is incubated determines the sex of the offspring. In TSD reptiles, yolk steroids not only may influence sex determination, but also may mediate hormonal effects on subsequent growth and behavior, as in some avian species. We investigated changes in the levels of estradiol (E(2)) and testosterone (T) during development in yolks of snapping turtle eggs, examined how incubation… CONTINUE READING
