Answer

Answer:

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

Explanation:

Step1: Determine phenotype from genotype

In genetics, for a trait with dominant (D) and recessive (d) alleles, the genotypes (DD), (Dd) show the dominant phenotype (dimples), and (dd) shows the recessive phenotype (no dimples).

Step2: Count genotypes in Punnett - square

In the given Punnett - square, the genotypes are (DD), (Dd), (Dd), (dd).

Step3: Count phenotypes

There are 3 genotypes ((DD), (Dd), (Dd)) that result in the dimple phenotype (dominant) and 1 genotype ((dd)) that results in no - dimple phenotype (recessive).
