A Client Is Not Certain Whether She and Her Family

A client is not certain whether she and her family should participate in a genetic screening plan.She asks the nurse why the X-linked recessive disorder that has been noted in some of her family members is expressed in males more frequently than in females.What is the nurse's best response?

A) "The disease tends to show up in males because they don't have a second X chromosome to balance expression of the gene."
B) "One X chromosome of a pair is always inactive in females. This inactivity effectively negates the effects of the gene."
C) "Females are known to have more effective DNA repair mechanisms than males, thus negating the damage caused by the recessive gene."
D) "Expression of genes from the male's Y chromosome does not occur in females, so they are essentially immune to the effects of the gene."
