Question

the punnett square predicts the ratio of genotypes in the offspring, based on the genotypes of the parents. the punnett square below examines the chance of offspring having freckles, which is a dominant trait.

\t\tf\tf
f\tff\tff
f\tff\tff

based on the punnett square, what is the probability that the offspring will have freckles?

25 percent
50 percent
75 percent
100 percent

Explanation:

Step1: Identify dominant trait

Freckles (F) is dominant, so genotypes FF, Ff show freckles; ff does not.

Step2: Count favorable outcomes

From Punnett square: FF, Ff, Ff (3 out of 4) have freckles.

Step3: Calculate probability

Probability = $\frac{\text{Favorable}}{\text{Total}}$ = $\frac{3}{4}$ = 75%.

Answer:

75 percent
