Question
Which of the following is FALSE about X-linked recessive disease? A. Males have a higher chance of having the disease than females B. Males can inherit the disease from their mothers C. Fathers can pass the disease to their sons D. Females can be carriers of their sons
Correct Answer
Option C is the correct answer.
Detailed Explanation
Fathers pass their X chromosome to daughters, not to sons (sons get the Y chromosome from father). Therefore, an affected father cannot pass the X-linked recessive allele to his son. The son inherits the X from his mother.
Hint
Think about which parent gives which chromosome to a son.
