Feedback:
In X-linked recessive diseases such as hemophilia A, females who inherit the affected gene will be heterozygous, and, because a normal gene is also present, the expression of the disease will be blocked. But because males have only one X chromosome, the disease will be manifested in any male children who receive the affected gene from their mother. If the mother has the affected gene on one of her X chromosomes and the father is disease free, the chances are 50% a male child will manifest the disease and 50% a female child will carry the disease gene. All male children will not inherit the disease. All female children will not be a carrier of the disease. Females will not inherit the disease.
