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

Answer

Explanation:

Step1: Identify dominant - trait genotypes

The dominant allele for freckles is F. Genotypes with at least one F (FF, Ff) will show freckles.

Step2: Count total and favorable genotypes

There are 4 total genotypes in the Punnett - square (FF, Ff, Ff, ff). The favorable genotypes (with freckles) are FF, Ff, Ff, so there are 3.

Step3: Calculate the probability

The probability $P$ is the number of favorable outcomes divided by the total number of outcomes. So $P=\frac{3}{4}= 0.75$ or 75%.

Answer:

75 percent
