Question

Explain why x-linked recessive traits appear most often in male offspring?

Answer 1

Consider what females get as opposed to males. If you have a recessive trait on an X chromosome, where would you find the analog to a dominant trait?

Answer 2

Kainui's logic is right on the money.

Answer 3

Because females have two x chromosomes and males only have one. A woman is much more likely for that recessive trait to be hidden by a dominant one while a man doesn't get that opportunity because x and y chromosomes carry different genes.
