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.

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? Create a Punnett square to support your answer.

(2) Two Dalmatians had a large litter of 10 puppies. Seven of them have black spots, while 3 do not. What would the genotypes of the two parents need to be for this result? Create a Punnett square to support your answer.
