Create a hypothesis: Plant and grow the P1 and F1 seeds. Open the Develop hypothesis window and fill in all of the possible genotypes for P1, F1, and P2 as you did before. Suppose you started with the hypothesis that the P1 plants were anl/anl, YGR/YGR and the P2 plants were ANL/ANL, ygr/ygr. If that were true, what would be the genotype of the F1 plants?

Keeping in mind the life cycle of bacteriophages, consider the following problem: during the reproductive cycle of a temperate bacteriophage, the viral dna inserts into the bacterial chromosome where the resultant prophage behaves much like a trojan horse. it can remain quiescent, or it can become lytic and initiate a burst of progeny viruses. several operons maintain the prophage state by interacting with a repressor that keeps the lytic cycle in check. insults (ultraviolet light, for example) to the bacterial cell lead to a partial breakdown of the repressor, which in turn causes the production of enzymes involved in the lytic cycle. as stated in this simple form, would you consider this system of regulation to be operating under positive or negative control?
