A) The Y chromosome has fewer genes than the X chromosome, and most of them are related to male sex determination rather than dominant traits.
B) A woman can be a carrier of a sex-linked trait if she has one gene for that trait on one of her X chromosomes.
C) This statement is false; there is no dominant gene on the Y chromosome that can be expressed when the corresponding gene on the X chromosome is missing.
D) This statement is false; the Y chromosome does not have a corresponding gene for every gene on the X chromosome.
E) This statement is false; men cannot be carriers of sex-linked traits since they have only one X chromosome and any gene on it will be expressed.
F) This statement is true; a daughter acquires a sex-linked trait from both parents since she inherits one X chromosome from each parent, while a son acquires such a trait only from his mother since he inherits his Y chromosome from his father and only one X chromosome (from his mother).
