Which percentage indicates the chance that a daughter of a hemophiliac will be a carrier?

Question

Quizplus · Accepted Answer

Hemophilia is a sex-linked recessive trait. A daughter receives one X chromosome from her mother and one from her father. If the father is hemophiliac (has the hemophilia allele on his X chromosome), and the mother is not a carrier, the daughter must receive the hemophilia allele from her father (since he has only XhY genotype, where Xh is the hemophilia allele), making her a carrier (XhX). Therefore, all daughters of a hemophiliac father will be carriers, which is 100%. However, since the question does not specify the mother's genotype and assumes a general scenario, the correct interpretation of the question seems to be flawed. The correct understanding should be that daughters have a 100% chance of being carriers if the father is hemophiliac and the mother's genotype is not considered.
