Question

If the father is unaffected by an X linked recessive disorder then his daughters will also not inherit the disorder.

• A. True
• B. False

Answer 1

The correct option is A

True

Father, being a male, has only one X chromosome. If he is unaffected, it means the X chromosome he passes on to the next generation is normal. All the daughters will inherit the normal X chromosome from him. Hence the daughters will not be affected. But they can become carriers if they receive defective X chromosome from mother.
