Two parents with dimples have a child with no dimples. The allele [tex]D[/tex] for dimples is dominant. What are the possible genotypes of the parents?
I. [tex]DD[/tex] and [tex]Dd[/tex]
II. [tex]Dd[/tex] and [tex]Dd[/tex]
III. [tex]DD[/tex] and [tex]dd[/tex]
A. I only
B. II only
C. I or II
D. II or III
E. I, II, or III
Answer (2)
I am pretty sure D is the answer
The possible genotypes of the parents are specifically D d and D d . This combination allows for the possibility of having a child with the genotype dd , which expresses no dimples. Thus, the correct choice is B. II only.
