A phenotype is a physical characteristic which is visible. Hence when the resulting combinations have two dominant alleles or even one dominant allele, the dominant characteristic is exhibited. The recessive characteristic is exhibited only when both the alleles are recessive.
To find the ratio of phenotypes, we need to place the genotype of the father and mother in a grid form ( attached grid figure)
Here we have two Ff phenotypes which is dominant and two ff phenotypes which is recessive
Hence the ratio is 2:2 or 1:1
