Hemophelia is an X-linked recessive disorder. A mother without the allele and a father with the allele have a daughter. The daughter then marries a man with hemophilia. What is the genotype of the daughter? What is the probability that the daughter's
children will develop the disease?
What will be an ideal response?
A Punnett square will show that the daughter must be heterozygous. A Punnett square of the daughter and her husband will show that 50 percent of the children will have the disease.
