In an experiment, 1000 rodents were released into a light brown sandy area where no rodents previously existed. the rodents’ fur color was either brown, black, or tan. there was a known predator of the rodents in the same area.
after several generations, what fur color frequency would a researcher expect to see?
a) rodents of all three fur colors will maintain the same frequency, as they are at equilibrium for all genes in the gene pool.
b) rodents with brown fur color will decrease in frequency since they will be outcompeted by both lighter and darker furred rodents.
c) rodents with black fur color will decrease in frequency as they are more visible to the predator against the light sand background.
d) rodents with tan fur color will decrease in frequency as they are unable to absorb as much solar radiation as darker mice and will have access to less free energy.
