Which of the following is a correct example of natural selection? A. The DNA of a frog changes due to radiation, chemicals, or some
other mutagen.
B. A population of frogs experiences a change in allele frequencies as
more frogs immigrate into the population.
C. Poisonous frogs with warning coloration are less likely to get eaten
by predators. Individual frogs therefore develop warning coloration
and poison during their lifetimes. These acquired characteristics are
passed on to their offspring.
D. Certain members of a frog population are better camouflaged, so
they survive and reproduce more, passing on their color genes.
