Question 9 (Biology)

Duchenne muscular dystrophy (DMD) is a sex-linked recessive disorder that results in a degenerative disease of the muscles of the body. As muscles gradually deteriorate, patients lose the ability to control the muscles and eventually die as breathing muscles are rendered useless. An extended family was studied over several generations and the incidence of DMD was followed as indicated in the pedigree below.

Using the lower case letter d as the recessive allele for DMD, what is the genotype of the individual labeled "C" in the pedigree?
