Suppose that your father is heterozygous for a recessive disorder. Also suppose that you know your mom has two "good" alleles. What is the probability that you will have the disorder?

Question

Quizplus · Accepted Answer

Since your mother has two "good" alleles, she can only pass on a "good" allele. Your father, being heterozygous, has one "good" allele and one "bad" allele. Therefore, you will always inherit at least one "good" allele from your mother, ensuring you do not have the disorder.
