If gametes were diploid like somatic cells, how many chromosomes would the zygote contain? if gametes were diploid like somatic cells, how many chromosomes would the zygote contain? half the diploid number with no change in development twice the diploid number, and with every succeeding generation, the chromosome number would continue to double and normal development could not occur. triple the diploid number, and with every succeeding generation, the chromosome number would continue to triple and normal development would not occur. there is no relationship between gametes and somatic cells.

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?
