Question
Two parents are unaffected by an autosomal dominant disorder. What is the probability that their offspring will be affected?Group of answer choices0%50%75%25%
Solution
The probability is 0%. If a disorder is autosomal dominant, it means that only one copy of the disease-causing allele is necessary for an individual to be affected. If both parents are unaffected, they do not carry the disease-causing allele, and therefore cannot pass it on to their offspring.
