a couple has just learned that their daughter has hemophilia. they already have a son who does not have a disease. What are the genotypes of the couple? Explain your reasoning in full sentences
Hemophilia is an X-linked recessive disorder. Since the daughter
inherits one copy of X chromosome from each of her parents, and with
hemophilia being a recessive disease, the daughter must inherit both
copies of recessive hemophilic gene.
X-linked hemophilic gene: X₀ Genotype of mother: X₀X Genotype of father: X₀Y
