A. Analyze the pedigree below and determine if the trait is inherited as autosomal dominant, autosomal recessive, X-linked dominant, X-linked recessive, or Y-linked. Remember, data from human families is limited, so you may be unable to determine the inheritance with certainty. The key is that you justify your answer using data from the pedigree. 2 4 0-4

B. Two family members (individual four and individual 12) decide to undergo
genetic counseling and testing for the disease.

• Genetic testing also indicates that individual 12 has only mutant allele(s)
Does this information change your assessment of the inheritance of the disease? If
so, explain why; if not, explain why not.
