Cystic fibrosis is an inherited disorder that affects cell membranes. It is caused by a recessive allele, f.

a) A woman is a carrier for cystic fibrosis, and her partner is homozygous dominant. Complete a Punnett square to show the possible genotypes of their children. Use F for the dominant allele and f for the recessive allele.

b) State the probability that a child born to this couple will have cystic fibrosis. Give your answer as a percentage.

c) Polydactyly is another inherited disorder where a person has extra fingers or toes. Explain why a child only needs to inherit one copy of the polydactyly allele to express the phenotype, whereas they need two copies for cystic fibrosis.
