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. f f f ff ff f ff ff 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 genotypes for freckles

Since freckles is a dominant trait, genotypes FF and Ff will result in freckles.

Step2: Count total genotypes

There are 4 total genotypes in the Punnett - square: FF, Ff, Ff, ff.

Step3: Count genotypes for freckles

There are 3 genotypes (FF, Ff, Ff) that result in freckles.

Step4: Calculate probability

The probability is the number of favorable outcomes (genotypes for freckles) divided by the total number of outcomes. So the probability $P=\frac{3}{4}= 75\%$.

Answer:

75 percent
