Question
The questions below all refer to the following pedigree. The locus for allele D/d determines how cilia
function within the body. Mutations at this allele cause abnormal ciliary function, resulting in a clinical
disorder characterized by frequent respiratory infections (including in the ears, sinuses, and lungs), as
well as infertility. In the pedigree, black circles/squares represent individuals affected by the disorder.
White circles/squares represent unaffected individuals. Remember, if a trait is rare in a population
(such as this one), we assume individuals marrying into the family are NOT carriers unless the
information provided indicates otherwise.

1) What is the probability that B3 is a carrier of this disorder? Show your work with a Punnett Square
in addition to stating the probability (1 pt).
Os
2) Individuals C2 and C3 are considering having additional children. However, having already had a
child with this disorder, they visit a genetic counselor to determine what the probability is that their
future child would have the disorder. If C2 and C3 have another child, what is the probability that the
child will have the disorder? Show your work with a Punnett Square in addition to stating the
probability (1 pt).
D5
3) D5 goes on an exotic vacation and meets the love of her life, Taylor. It is determined that 5% of the
population where Taylor lives is a carrier for this disorder. If we assume Taylor has the same risk of
being a carrier as everyone else in their population (5%), what is the probability that D5 and Taylor
will have a child with the disorder? Show your equation and explain for full credit (3pts)
Final probability that D5 and Taylor would have an affected child:
