Studies the genetic, molecular, cellular and morphological changes that occur during development. Current mechanistic concepts in development will be presented along with classical embryology to provide a comprehensive understanding of the processes that direct a fertilized single-celled egg to develop into a complex multi-cellular organism. Particular attention will be paid to recent molecular mechanisms of development. This is a graduate level course with three hours of lecture/seminar per week. The prerequisite is admission to the M.S. program in biology. Not offered every semester.
