no, a man will never pass an x linked trait on to his son, a man gives only a y chromosome to a son and the son gets the x chromosome from the mother.


however the father will always pass it on to the daughter, so every daughter would be a carrier.


just because its genetic doesn't mean anything, just that it gets passed on but there are different types of inheritance





and to the person above me since it is x linked the son would only need one because he only has one x, a daughter would still need two..you would be correct if it was an autosomal recessive trait, but this is sex linked.
Reply:Yes, and men are more likely to get sex-related (NOT STDs, theyre different) diseases than girls, because they have one sex chromosome, whereas girls have two=girls need both to be messed up, but men only need one P.S. red-green colorblindness is passed through the sex chromosome
Reply:No, red-green colorblind is on the X chromosome. The man gets it from his mother. He can not pass it to his son, but he can pass it to his daughters.
Reply:its a recessive trait.. so theres a possibilty that his son may be blind
Reply:Yes. It is genetic so it can be passed on.
