22. For the pedigree at right, if H = wookie hair and h=normal body hair, identify the genotype of person B.

a) Person B is hh.

b) Person B is Hh.

c) Person B is either HH or Hh. (Because they are shaded in, person B has wookie hair. Because wookie hair is dominant, this means person B's genotype is most likely HH (since they have no hh kids), although Hh is also possible.)
