Tony has anosmia, a disorder that prevents him from being able to smell. This disorder is an X-linked recessive condition. Tony's wife Samantha has a normal sense of smell. Tony's sister Hailey also has a normal sense of smell as does her husband Phil and daughter Sandra. However, Hailey and Phil also have identical twin boys, Josh and Andre, and neither of them can detect odors. Tony and Hailey's parents, Tom and Dolores can smell normally.   Draw a pedigree for this family indicating the individuals who must be carriers of the anosmia mutation as well as the genotype of each individual. Take a
