Jonah and Jana are siblings. Jonah has the genetic disorder cystic fibrosis, caused by inheriting two mutant alleles of the CFTR gene (the gene that when mutant causes cystic fibrosis) - one allele was inherited from each parent. Jana does not have cystic fibrosis. Which of the following statements is/are true? Jana does not have the CFTR gene. Jana has two copies of the CFTR gene. Jana has at least one copy of the non-mutant allele of the CFTR gene. Jana has two copies of the mutant allele of the CFTR gene.

Please fill in the following red areas.

Genetic Inheritance Patterms 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 (i.e., you must get a copy of the defective gene from your Mom and one from your Dad). Autosomal means it is not carried on one of the chromosomes that determines sex. Usher's Type II is recessive, so 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 and chances of having RP. Your pedigree must include his parents, Eric, his brother Dirk, and a potential daughter of Eric's. Draws a pedigree that shows the correct genotypes and chances of having retinitis pigmentosa for Eric and his family. D.Focus (United States) a S W 37 F 八 口
