Females have two X chromosomes, allowing them to be carriers of X-linked traits. They can pass these traits to their offspring without expressing the trait themselves if it is recessive. This is because females can inherit and carry a recessive gene on one of their X chromosomes without it being expressed, as the dominant gene on the other X chromosome can mask the effect of the recessive gene.
