Assume earlobe shape is controlled by a single gene with two alleles. the dominant allele generates free earlobes, while the recessive allele produces attached earlobes. a second gene on a different chromosome controls earwax consistency, where wet is dominant and dry is recessive. bella has free earlobes with wet earwax and is heterozygous for both traits. edward has attached earlobes with dry earwax. what is the probability that their first child will have either free earlobes or wet earwax or both dominant traits?

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?
