Genetic Concepts for Medical-Surgical Nursing

Question 1 of 5

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 traits.

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-chromosomes, which allows two X-linked recessive disorder to be transmitted from father to son.
