Question

Having dimples (D) is dominant over not having dimples (d). A dimpled woman (whose father had no dimples and whose mother did have dimples) marries a man whose mother had no dimples, whose father had no dimples, and whose grandparents on his father’s side did have dimples! What is the man's genotype.

A: Dd

B: dd

C: DD

Answer 1

dd

Step-by-step explanation:

Even though the father's parents had dimples, he inherited the dd genotype.

He doesn't have DD or he would've had dimples.

He doesn't have Dd or he would've had dimples due to D being dominant.
