If having dimples is dominant (D) and not having dimples is recessive (d), which of the following correctly describes the phenotypes in the table?
A.
all of the offspring have dimples
B.
two of the offspring have dimples and two do not have dimples
C.
three of the offspring have dimples and one does not have dimples
D.
all off the offspring will not have dimples

Answer 1

C. Three of the offspring have dimples and one does not.

Explanation: DD and Dd express the dominant dimple trait, dd does not. The four genotypes in the square are DD, Dd, Dd, and dd, so 3 show dimples and 1 does not.
