Predict whether the GAL gens (Gal1, Gal7 Gal10 and Gal2) will be produced in the following yeast strains under the conditions noted. Use + to indicate that the GAL enzymes are synthesized at greater than basal levels, and 0 to indicate that the enzymes are not synthesized. Question 3 (10 points) Shown below is a list of gene classes that play a role in Drosophila development. Homeotic genes Gap genes Segment-polarity genes Maternal-effect genes Pair-rule genes (i) Describe the role of each class of genes and the impact that a mutation in the class has on Drosophila development. (ii) The different classes of genes function at different times during Drosophila development. Put the gene classes in order, from earliest to latest. .
