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. 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 genotypes

The dominant trait for freckles is represented by F. Genotypes with at least one F (FF, Ff) will show the freckles trait.

Step2: Count genotypes with dominant trait

In the Punnett - square, there are 3 genotypes with at least one F (FF, Ff, Ff) out of 4 total genotypes.

Step3: Calculate probability

The probability is $\frac{3}{4}= 75\%$.

Answer:

75 percent
