In humans, freckles are a trait that exhibits simple dominance. The two alleles for this trait are freckles (A) and no freckles (a). A freckled man whose mother has no freckles marries a woman with no freckles. What is the probability that their first child will have freckles? Use the Punnett square to show your work.

It is Aa and aa, so that is 50%

Explanation:

This is because the chances are Aa & aa: The results look like Aa for top right and top left and aa for bottom right and bottom left.

50 percent

Explanation:

Aa goes with aa

so their children's genotypes would be

Aa Aa aa and aa

so two with freckles and two without freckles which is why their first child has a 505 chance of having freckles
