X-linked inheritance means that the gene causing the trait or the disorder is located on the X chromosome. Females have two X chromosomes, while males have one X and one Y chromosome.
The inheritance pattern may be recessive or dominant. The trait determined by a gene on the X chromosome is always expressed in males. Transmission from father to son does not occur. Kinds of X-linked inheritance are X-linked-dominant inheritance and X-linked recessive inheritance. Compare autosomal inheritance. See also sex-linked.
