Question
**Genetic Inheritance Patterns** Retinitis Pigmentosa (RP) can be autosomal recessive, autosomal dominant, or X-linked. Apparently, the dominant forms are often less severe. Eric's form of RP is Usher's Syndrome, which is an autosomal recessive inheritance. You must get a copy of the defective gene from both Mom and Dad to have RP. For Eric, this means that both his mom and dad are carriers of this condition. His brother, Dirk, does not have any symptoms of RP. Draw a pedigree of Eric's family showing possible genotypes. Your pedigree must include his parents, Eric, his brother Dirk, and a potential daughter of Eric and his family. Assign the genotypes and chances of having RP. Your answer should include the most common genotypes and chances of having retinitis pigmentosa for Eric and his family.
