Answer:
e) Sons and daughters have equal probabilities in inheriting a recessive allele of an X-linked gene from their mother, but only sons can inherit rare Y-linked genetic disorders from their father.
Explanation:
Females have two copies of the X chromosome and males have only one X chromosome (one Y chromosome). Because of that X-linked recessive diseases are more common among males than females (males need only one copy to have disease, females with one copy are carriers).
For example, if a mother is a carrier (has only one allele that is associated with disease), she can transmit either the X chromosome with the mutation or an unaffected X chromosome to her children. If the father is unaffected, all of the daughters will be unaffected—since they will inherit at least one normal X chromosome from their father. But, son can be affected, because he inherits Y chromosome from father and can inherit affected X chromosome from mother.
