- Explain the functional roles of maternal-effect genes, gap genes, pair-rule genes, and segment-polarity genes in Drosophila development.Describe the role of coordinate genes, gap genes, pair rule genes, segment polarity genes, and homeotic genes in Drosophila development.Describe the relationship between homeotic genes in Drosophila and in mice.
- provide one example from the Drosophila AP toolkit for "Toolkit genes can be classified according to the phenotypes caused by their mutation. Similar mutant phenotypes often reflect genes that function in a single developmental pathway. Distinct pathways exist for the generation of body axes, for example, and for the formation and identity of fields."Explain the Drosophila genetics tool for gene expression known as the UAS-GAL4 systemDescribe the expression pattern of the Drosophila geneeve in the early embryo.
- It seems that developmental genetics boils down to a complex network of gene regulation. Try to draw a structure of this network for Drosophila. How many genes do you think are necessary to complete the developmental network for the fruit fly? How many genes do you think are needed for a network to specify one segment? Do you think it is more difficult to identify genes that are involved in the beginning, middle, or end of this network? Suppose you were trying to identify all of the genes needed for development in a chicken. Knowing what you know about Drosophila development, would you first try to identify genes necessary for early development, or would you begin by identifying genes involved in cell differentiation?Discuss the role of homeotic genes in development. Explain what happens to the phenotype of a fruit fly when a gain-of-function mutation in a homeotic gene causes the protein to be expressed in an abnormal region of the embryo. What are the consequences of a loss-of-function mutation in such a gene?How have we discovered that specific genes control development in an organism like Drosophila?
- Explain the Retrotransposons—the Copia –White-Apricot System in Drosophila ?Describe the formation steps of the primary axis that first occurs during development in Drosophila by explaining each molecule.Compare and contrast the experimental advantages of Drosophila and C. elegans in the study of developmental genetics.
