A population of Poison dart frogs can be red (RR), orange (Rr) or yellow (rr). The allele frequency of the mainland is R: 0.5 r: 0.5. A small group of
the frogs moves to an island off the mainland. If the group is composed
of 4 red and one orange frog, what would you expect to happen to the
allele frequency?
A. Increase towards the r allele
B. Frequency of both alleles would decrease
C. Increase towards the R allele
D. Stay the same as the mainland
