Question

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

Explanation:

For X - linked recessive traits, males have one X and one Y chromosome. If they inherit the recessive allele on the X chromosome, they will express the trait (since there's no dominant allele on the Y to mask it). Females have two X chromosomes, so they need to inherit two recessive alleles (one from each parent) to express the trait, which is less likely. Thus, more males than females express X - linked recessive traits.

Answer:

More males than females express the trait.
