  • Card 6 / 15:
    Why do mammalian eggs have a small concentration of yolk, while bird and reptile eggs have a large concentration of yolk?

    Mammalian eggs do not need a lot of yolk because the developing fetus obtains nutrients from the mother. Other species, in which the fetus develops outside of the mother’s body, such as occurs with birds, require a lot of yolk in the egg to nourish the embryo during development.
