In Dalmatians, the trait for black spots (B) is dominant over the recessive trait for no spots. Use this information to answer these questions. (1) Two Dalmatians with black spots have puppies. One of the dogs is homozygous for black spots, while the other is heterozygous. Out of a litter of 4 puppies, how many would you expect to have without spots?

FALL FINAL 2013 REVIEW
Some people have dimples, while others do not. The presence of dimples is a dominant trait (D), while not having dimples is recessive (d). (1) Susie has dimples, but her husband, Tom, does not. Their first child has his father's phenotype. What are the genotypes of the mother, father, and child?
Mother’s Genotype: _______
Father’s Genotype: _______
Son’s Genotype: _______
(2) What is the probability that a second child won’t have dimples? Create a Punnett square to support your answer.
