A Patient Is Not Certain Whether She and Her Family

question 6

Multiple Choice

A patient 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 do not have a second X chromosome to balance the 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."
