Question

read the article and use it to answer the question that follows. sex linked inheritance why are women often carriers of x - linked traits but rarely affected by them?

Explanation:

Women have two X chromosomes. For an X - linked recessive trait, a woman needs two recessive alleles (one on each X) to be affected. But she can have one recessive and one dominant allele, making her a carrier. Males have one X and one Y, so one recessive allele on X affects them.

Women have two X chromosomes. For X - linked recessive traits, they need two recessive alleles to be affected (rare, as they can inherit a dominant allele on the other X), but with one recessive allele, they become carriers.
