Question

Hemophilia is an inherited bleeding disorder where blood does not clot properly. This disorder is caused by a recessive allele on the x chromosome. a couple has just learned that their daughter has hemophilia. They already have a son who does not have the disease. what are the genotypes of the couple and the two siblings? explain your reasoning

Answer 1

Already answered this. Father must be hemophiliac to pass down his recessive hemophilia X. If he is not a hemophiliac, he is not the daughter's (double recessive X) biological father. Mother has one recessive hemophilia X and one dominant X. The dominant X went to the son.
