Answer

Answer:

expresses hemophilia

Brief Explanations:

In the pedigree, John (the shaded - square offspring of Charles and Marie) has the genotype associated with hemophilia. Shaded symbols in a pedigree often represent individuals with the trait in question. Since hemophilia is an X - linked recessive disorder and John is male, having the recessive allele on his X - chromosome (as indicated by the inheritance pattern from his carrier mother Marie) means he expresses hemophilia.
