Which of the following statements about hemophilia is true?

• A. It only affects women
• B. Males can inherit this disorder from their fathers
• C. It is common among women
• D. All hemophiliacs are asymptomatic

Answer: (B)

The statement that males can inherit hemophilia from their fathers is indeed true. Hemophilia is a genetic disorder typically passed through the X chromosome. Since males have one X and one Y chromosome, they inherit their single X chromosome from their mothers. As a result, they cannot inherit hemophilia directly from their fathers, who pass on the Y chromosome. However, it is important to note that females can inherit hemophilia if they receive the affected X chromosome from both parents or are carriers with one affected and one normal X. While males are more commonly affected due to having only one X chromosome, the inheritance pattern among different genders is crucial for understanding the transmission of hemophilia. In contrast, the other statements are inaccurate. The disorder does not exclusively affect women, as it predominantly impacts males. It is also not common among women as they are generally carriers if they do not express the disorder unless they have mutations on both of their X chromosomes. Lastly, hemophiliacs often experience various symptoms related to bleeding tendencies rather than being asymptomatic.
