What is a major advantage of using a modifier screen as opposed to a primary screen? Multiple Choice O Modifier screens are easier to perform o Modifier screens are performed with chemically mutagenized flies so all genes that affect development should be identified more rapidly than screening for spontaneous mutants O Modifier screens can be used to identify pleiotropic genes. Modifier screens use a random selection of flies based on their morphology and therefore should identify all genes involved in...
2. A dominant allele H reduces the number of body bristles that Drosophila flies have, giving rise to a “hairless” phenotype. In the homozygous condition, H is lethal. An independently assorting dominant allele S has no effect on bristle number except in the presence of H, in which case a single dose of S suppresses the hairless phenotype, thus restoring the "hairy" phenotype. However, S also is lethal in the homozygous (S/S) condition. What ratio of hairy to hairless flies...
How can we assess whether a project is a success or a failure? This case presents two phases of a large business transformation project involving the implementation of an ERP system with the aim of creating an integrated company. The case illustrates some of the challenges associated with integration. It also presents the obstacles facing companies that undertake projects involving large information technology projects. Bombardier and Its Environment Joseph-Armand Bombardier was 15 years old when he built his first snowmobile...
