Question

Quizplus · Accepted Answer

Daughters of affected males are usually carriers of X-linked disorders because they inherit one X chromosome from their affected father and one X chromosome from their unaffected mother. While sons have a 50% chance of inheriting the affected X chromosome from their mother and developing the disorder, daughters have a 50% chance of inheriting the affected X chromosome but usually do not develop the disorder because they have a second, unaffected X chromosome to compensate. Therefore, daughters are usually carriers of X-linked disorders.
