Answer:

25%

Step-by-step explanation:

Here is my punnett square:

                    D             d           <---parent 1

     D          DD           Dd

     d          Dd           dd

    ^

    |

    |  parent 2

The results: DD, Dd, Dd, dd

DD, Dd: will have dimples because they have a dominant allele in their genotype. So in their phenotype, they will have dimples.

dd: will not have dimples because they do not have the dominant allele for dimples in their genotype. So in their phenotype, they will NOT have dimples.

3 cases (25% chance for DD, 50% chance for Dd, 25% chance for dd)

1/4 is DD is 25%

2/4 is Dd is 50%

and 1/4 is dd is 25%

answer: 25%

Have a nice day!
