PLEASE HELP Colorblindness is a recessive trait that is passed along to human offspring. The
inability to differentiate between or see some colors is controlled by a gene that is
found on the X chromosome. Why are more males affected by colorblindness than
females?
Colorblindness is more often found in males because they have less of a need to
see color
Colorblindness is more often found in males because they receive only one Y
chromosome and therefore men always will have colorblindness because
females do not have a Y chromosome
Colorblindness doesn't occur more often in males it happens equally in both
male and females

Which statement about inheritance is true? o girls get most of their traits from their moms, boys get most of their traits from their dads. o male offspring will always have an x-linked genetic disease if the mom is a carrier o fathers always determine the gender of the offspring in humans. o males never have y chromosomes.

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?
