A woman and man have the following genotypes for an autosomal dominant disease: Aa and Aa. If asked, which of the following should the nurse say is the probability of their child having the disease?

  • A. 25% probability.
  • B. 50% probability.
  • C. 75% probability.
  • D. 100% probability.
Correct Answer: C

Rationale: The probability of their child having the disease is 75% because both parents are carriers (Aa). The possible genotypes for the child are AA, Aa, aA, and aa. Only the aa genotype would not result in the disease, giving a 75% chance of the child having the disease.
