X-linked or sex-linked traits can express in both males and females, but they are more commonly expressed in males because males have only one X chromosome, so a single recessive allele on the X chromosome will express the trait. In females, who have two X chromosomes, a recessive allele must be present on both X chromosomes to express the trait.
