In which of the following scenarios is the offspring most likely to express the genetic condition?

Only the father is a carrier for an X-linked recessive condition. The offspring is a male.
Both parents are a carrier for an autosomal recessive condition. The offspring is a female.
Only the mother is a carrier for an X-linked recessive condition. The offspring is a female.
Only the mother is a carrier for an X-linked recessive condition. The offspring is a male.

The offspring in the scenario where only the mother is a carrier for an X-linked recessive condition and the offspring is male is most likely to express the genetic condition. This is because males only have one X chromosome, inherited from their mother, so if the X chromosome carries the recessive gene, the male offspring will not have a corresponding dominant allele from the Y chromosome to mask the effects of the recessive gene.
