The color of blood depends on how much oxygen is in the blood; when here is plenty of oxygen, the blood is more reddish in color. The reason that this is so is because of a protein called HEMOGLOBIN, which carries the oxygen in your blood. When hemoglobin has a full oxygen load, it gives the blood a reddish color.
Egg Incubation. A female alligator lays between 35 and 90 eggs. Once the eggs are laid, she covers them with a layer of vegetation to keep them warm. The incubation period is 65 days and the temperature within in the nest plays a critical role during this time.
All of these eggs hatched female offspring. Eggs incubated at 34 degrees centigrade (93.2 degrees Fahrenheit) in the same period resulted in all male offspring. The reason, Cardeilhac said, is that alligators lack sex-determined chromosomes, so temperature determines their gender. Temperatures 34 degrees centigrade and above produce androgenic hormones inside the egg, which form male sex organs.
