In presenting this topic, there are two expository goals. The first is to study repro duction at all of the major levels of biological organization-from the molecular (e. g., hormone receptors in the brain), through the cellular (e. g., ovarian morphogene sis), systemic (e. g., operation of the hypothalamo-pituitary-ovarian axis), and the organismic levels of organization. Analogously, behavior is treated from the most molecular,...
