A daughter can inherit an X-linked recessive disorder if

Question

Quizplus · Accepted Answer

An X-linked recessive disorder is passed down from the mother who carries the gene mutation on one of her X-chromosomes. If the father has the disorder, he will pass it on to all of his daughters but none of his sons. If the father is hemizygous for the disorder and the mother is wild type, none of their daughters will inherit the disorder. If both parents are carriers, there is a 25% chance that their daughter will inherit the disorder. If the mother is affected with the disorder, all of her sons will inherit it but none of her daughters will. If the father is a carrier, there is a 50% chance that his daughters will inherit the disorder. Therefore, choice A is the best option as it describes a scenario where the mother is a carrier and the father has the disorder, allowing the daughter to inherit the disorder.
