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: Understand dominant trait

A dominant trait (like freckles here) is expressed when the genotype is \(FF\) or \(Ff\).

Step2: Count favorable genotypes

In the Punnett square, there are 4 total genotypes (\(FF\), \(Ff\), \(Ff\), \(ff\)). The favorable genotypes (\(FF\), \(Ff\), \(Ff\)) are 3.

Step3: Calculate probability

Probability \(P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}=\frac{3}{4} = 0.75\) or 75%.

Answer:

75 percent
