heres the question, I totally don't understand it:

a few sex linked ttraits in humans are located on the Y chromosome and are dominant. What pattern of inheritence would uou expect to see in these traits? show your exmaplantion.

  • BIO -

    If the traits are on the y-chromosome, and are DOMINANT...that means that ALL the offspring BOYS will have the trait, but NONE of the offspring GIRLS will have the trait. Do you see why?

  • BIO -

    is it because in order for there to be a boy the dad would have to give a y because a mom can only give x and since the y is domiannt it would always express the trait>?

  • BIO -

    Yes, absolutely right!!!
