In a population of fish, the frequency of individuals with
speckled fins is 0.7 and the frequency of individuals with banded
fins is 0.3. Assume the pattern is determined by two alleles of one
gene, and assume the fish show a very good fit to the H-W
Model.
a. What genotype frequencies do you expect if speckled is the
dominant trait?
b. What genotype frequencies do you expect if banded is the
dominant trait?
