Learning objectives for this class Organize the different events involved in anterior-posterior patterning in sequential order and name the main genes implicated Relate the different mechanisms employed to pattern the embryo back to the developmental stage when they occur Explain forward genetics and how this approach has lead to gene discovery Predict how loss of maternal components or associated proteins may perturb anterior-posterior patterning Explain how maternal gradients are established in the early embryo Explain what a morphogen is and how it functions

Nobel prize in physiology and medicine, 1995 Awarded for the discovery of "the genetic control of early embryonic development” in the fruitfly Drosophila. Genes identified have important functions during the early development of the human embryo. Example: formation of the body axis and the segmentation of the body. It is likely that mutations in such important genes are responsible for some of the
