The phenotype ratio would be 25% each for widow's peak and freckles, widow's peak without freckles, straight hairline with freckles, and straight hairline without freckles.
<h3>Dihybrid crossing</h3>
Genotype of the heterozygous parent: HhFf
Genotype of the other parent = hhff
Crossing the two parents:
HhFf = 1/4 = Widow's peak, freckles
Hhff = 1/4 = Widow's peak, no freckles
hhFf = 1/4 = straight hairline, freckles
hhff = 1/4 = straight hairline, no freckles.

Explanation:
Hormone is responsible to mediate change in the cell by binding to the hormonal receptor present on the cell. So hormone only acts on the cells which have the specific receptor for that hormone.
One cell can have many receptors for a single hormone which defines the sensitivity of cell for the hormone which is responsible for generating appropriated cellular response in the cell.
So the number of receptors on the cell can contribute to different responses of cells having the same hormonal receptor. Every cell also have unique transduction pathway which is also responsible for different response of cell.
Actually, its chance is 25%. A grey cat holds the alleles BW. A grey cat (BW) crosses with a black cat (BB). The percentage is 25% because the allele, “W” is present two times.
