Two heterozygous purple-stemmed plants are grown. Each parent has the genotype ANL/anl. Pollen from one of the plants is used to pollinate the other, and the resulting seeds are harvested. What traits would you expect in the plants grown from these seeds? A. All of the offspring plants will have purple stems. B. All of the offspring plants will have green stems. C. About half of the offspring plants will have purple stems, and half will have green stems. D. Most of the offspring plants will have purple stems, but some will have green stems.

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?
