A man with a certain disease marries a normal woman. They have eight children (3 daughters and 5 sons). All the daughters suffer from their father's disease but none of the sons are affected. Which of the following mode of inheritance do you suggest for this disease?
-
- Sex-linked recessive
- Sex-linked dominant
- Autosomal dominant
- Sex-limited recessive
Correct Option: B
The daughters receive one X chromosome from the father and one X chromosome from the mother. Since all the daughters suffer from their father’s disease, the X chromosome from the father must be carrying a dominant trait.
