A recessive, sex-linked trait in mice is determined by a gene
located on the X chromosome. If a female mouse that exhibits this

offspring be affected?
All of the female offspring and none of the male offspring would
exhibit the trait.
All male offspring would exhibit the trait, and all female
offspring would be carriers.
Half of the female offspring and all of the male offspring would
exhibit the trait.
Half of the male offspring would exhibit the trait, and all
