An experimental assay for the blood-clotting protein called factor IX is available. A blood sample was obtained from each member of the pedigree shown here. The amount of factor IX protein is shown within the symbol of each member and is expressed as a percent of the amount observed in normal individuals who do not carry a mutant copy of the gene.

What are the likely genotypes of each member of this pedigree?
