The following human pedigrees trace rare disease through multiple generations. Only phenotypes are represented (i.e. carriers are not identified). For each pedigree, determine: The most likely mode of inheritance. The probable genotype of the individual marked with an asterisk (*). Assume that the disease allele is rare. “Rare” means that individuals who marry into the family are very unlikely to have the defective allele. Explain your reasoning and include any ambiguities. Be sure to define your genotype symbols clearly.
