The Law of Independent Assortment states that Factors controlling different characteristics are inherited independently of each other. and the Law of Segregation states that Two factors of the same trait separate into different gametes. . For Independent Assortment to work on the genetic scale there must be More than one trait controlled by each gene. that align during Metaphase of meiosis 1. For Segregation to work on a genetic scale there must be Only one gene that controls the phenotype. that separate during Anaphase of meiosis 1.

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?
