Name: Date: 11 9J1 Block 1 Benchmark Quarter 3 Study guide Trait: Neurofibromatosis Forms of the trait: A The dominant form is neurofibmmatosis, caused by the production of an abnormal form of the protein neurofibromin. Affected individuals show spots of abnormal skin pigmentation and non-cancerous tumors that can interfere with the nervous system and cause blindness Some tumors can convert to a cancerous form A The recessive form is a pormal protein-in other words, no neurofibromatosis A typical pedigree for a famity that caries neurofibromatosis is shown below Note that carriers are not indicated with half-colored shapes in this chart. Use the letter "N" to indicate the dominant neurofibromatosis allele, and the letter "n" for the normal allele. Nn nn 3 nn 1. Is this autosomal or sex-linked? Why? 2.
