How will the frequency of the genes that result in long tails change over the next few
generations?
F Sexual selection will cause the genes that result in long tails to become less and
less frequent
G Sexual selection will cause the genes that result in long tails to become more
frequent
H The frequency of the genes that result in long tails will fluctuate slightly but
remain relatively stable.
J There is not enough information to draw a conclusion about future gene
frequency
