2. Answer the following questions based on the pedigree below. Affected individuals are shaded in. The squares represent male. The circles represent female. Assume the allele for the disease is rare and individuals who marry into the family are highly unlikely to carry the allele (6.0 pts).

a) What is the mode of the inheritance? How do you know? (Why can’t it be another mode of inheritance? Use examples.)

b)    Assign genotypes to each of the following individuals:

Row 1: genotype of father

Row 2: genotype of individual #1 (in order from left to right)

Row 2: genotype of individual #4 (in order from left to right)

Row 3: genotype of individual #7 (in order from left to right)

Row 4: genotype of individual #4 (in order from left to right)
