Answer

Explanation:

Step1: Identify dominant genotypes

The dominant allele for freckles is F. Genotypes with at least one F will show freckles. So FF, Ff are the genotypes for freckled - offspring.

Step2: Count total and favorable genotypes

There are 4 total genotypes in the Punnett - square (FF, Ff, Ff, ff). The number of genotypes that result in freckles is 3 (FF, Ff, Ff).

Step3: Calculate probability

The probability $P$ is given by the formula $P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. So $P = \frac{3}{4}=0.75$ or 75%.

Answer:

75 percent
