- How would you devise a screen to identify recessive mutations in Drosophila that result in embryo lethality? How would you propagate the recessive mutant alleles?Describe the construction of knockout mice?The anteriorposterior axis of a Drosophila embryo is first established by certain (a) homeotic genes (b) maternal effect genes (c) segmentation genes (d) proto-oncogenes (e) pairrule genes
- discuss the engineered embryronic stem cell method of obtaining gain of function transgenic miceDevelopmental genes act hierarchically during pattern formation, first defining broad regions, which aresecondarily refined to form a larger number of smaller regions. Summarize how this general principle isillustrated during the early stages of Drosophila embryogenesis.Gene dosage—the number of copies of a gene that areactively being expressed—is important to proper development. Identify and describe two processes that establish the proper dosage of certain genes.
