Hemophilia is a sex-linked recessive trait in humans. If a carrier female (heterozygous for the trait) mated with a nonaffected male, what would be the expected outcome(s)?

Question

Quizplus · Accepted Answer

Since hemophilia is a sex-linked recessive trait, a carrier female (XhX) mated with a nonaffected male (XY) would produce daughters who are either carriers (XhX) or not affected (XX) and sons who are either affected (XhY) or not affected (XY). Therefore, none of the daughters would have hemophilia, but half of the sons would inherit the Xh chromosome from their mother and have hemophilia.
