The average time to death from starvation in a fruit fly is about 20 hours. Selecting for increased starvation resistance in fruit flies:
a) can produce populations in which the average time to death from starvation is 10 hours.
b) has no effect because it is too complex a physiological process, dependent upon the effects of too many genes.
c) can produce populations in which the average time to death from starvation is 160 hours.
d) has little effect because constant mutation reduces starvation resistance, counteracting any benefits from selection.
e) has no effect because it is a not a trait that influences fruit fly fitness.
Ans: c) can produce populations in which the average time to death from starvation is 160 hours.
