he Punnett square predicts the ratio of genotypes in the offspring based on the genotypes of the parents. Which Punnett square represents a cross between a mom who is heterozygous for dimples and a dad who is homozygous for no dimples?

A Punnett square is shown. The columns are labeled Upper D and Upper D. The rows are labeled d and d. Clockwise from upper left the boxes contain: Upper D d, Upper D d, Upper D d, Upper D d.

The second Punnett square.

Mom (heterozygous) = Dd → gametes D and d. Dad (homozygous no dimples) = dd → gametes d and d. The square with columns D and d and rows d and d yields genotypes Dd, dd, dd, Dd (50% Dd, 50% dd), so half the offspring have dimples and half do not.
