Question

which outcome could be expected in a family that carries an x - linked recessive trait?
an equal number of males and females express the trait.
more females than males express the trait.
more males than females express the trait.

Explanation:

X-linked recessive traits are expressed when an individual has two recessive alleles (for females, XX) or one recessive allele (for males, XY, since they have only one X chromosome). Males need just one copy of the recessive allele to show the trait, while females need two, making males more likely to express the trait.

Answer:

More males than females express the trait.
