A nurse is educating a client about genetic screening. The client asks why red-green color blindness, an X-linked recessive disorder noted in some of her family members, is expressed more frequently in males than females. How should the nurse respond?
a. "Females have a decreased penetrance rate for this gene mutation and are therefore less likely to express the trait." b. "Females have two X chromosomes and one is always inactive. This inactivity decreases the effect of the gene." c. "The incidence of X-linked recessive disorders is higher in males because they do not have a second X chromosome to balance expression of the gene." d. "Males have only one X chromosome, which allows the X-linked recessive disorder to be transmitted from father to son."
