A True breeding Wild type fly was crossed with a True breeding Mutant fly to produce a Heterozygous F1. An F1 female was then crossed to a Test male. The results of this cross are as follows: cn vg 4202; cn 458; rd 4258; rd vg 482; cn rd 28; Wild Type 276; vg 32; cn rd vg 264. Which Phenotypes represent the Parentals i. s., the non- Cross Over Phenotypes from the F1 generation

And give a detailed description! scientist observes the boundary between two tectonic plates for a decade and finds that no new volcanoes have formed over the course of her investigation. does this result support the theory of plate tectonics? why or why not?

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?
