Answer:
F, F, f (if I'm understanding the question correctly)
Explanation:
Phenotypes are the physical trait shown. In FF, Ff, ff a capital letter means that the gene is dominant and therefore always shows when paired with either another of itself or a recessive (lowercase). So, for FF, you see F as the phenotype shown, and for Ff, you see F as the phenotype because F is dominant over the recessive f. In ff, however, since you have two recessives, only then can you see f as the phenotype because you have no dominant traits.
