4. Analyzing: 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. 5 2 7 11 14 8 12 15 3 13 4 10 B. Two family members (individual four and individual 12) decide to undergo genetic counseling and testing for the disease. • Genetic testing shows that individual 4 has only nonmutant allele(s) • 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.

B. Two family members (individual four and individual 12) decide to undergo
genetic counseling and testing for the disease.
• Genetic testing shows that individual 4 has only nonmutant allele(s)
• 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.
