Abstract
Marsupials have many characteristic features that make them ideal models to
study the control of sexual differentiation and development. They are
distinguished from eutherian mammals in their mode of reproduction and their
greater dependence on the teat and mammary gland than on the placenta for
development. They give birth to a highly altricial young which completes its
development while firmly attached to a teat, usually within the confines of a
pouch. At birth, the marsupial neonate has a well-developed digestive,
respiratory and circulatory system, but retains its fetal excretory system
with a fully functional mesonephric kidney and undifferentiated gonads and
genitalia.
