Two parents are heterozygous for cystic
fibrosis (CF). The father is also
heterozygous for Huntington disease (HD)
while the mother is normal for HD. Given
that the two parents had three normal
children answer the following: (use C to
indicate the normal allele for CF and c to
indicate the recessive allele, while use the
H to indicate the HD allele and h to
indicate the normal allele).
• What is the probability that their fourth child to
have CF?
• What is the probability that their fourth child to
have HD?
• What is their chance for having a child with both
diseases?
• How many possible gamete genotypes the father
may produce?
• What is the chance that child will have the allele
H?
