Make a punnett square and calculate phenotype %s?

Question

Gene C and Gene F are epistatic for a certain fish’s scale color. Gene C codes for the color (Cr = red, Cb= blue). A heterozygous offspring will produce a fish with purple scales. Gene F’s dominant trait codes for an enzyme that allows the pigmentation to enter the scales. Fish that lack this pigment have white scales. Two fish with the genotypes CbCbFF & CrCbFf are bred. Make a Punnett Square and provide the phenotype % for each phenotype.
