Perspectives from 5 Years of FOS. Concepts of dominance and recessiveness were initially used for autosomal traits, and then applied to 'sex'-linked traits to distinguish X-linked recessive and X-linked dominant inheritance. The former was defined as vertical transmission in which carrier females pass the trait to affected sons, while the latter was defined as vertical transmission in which daughters of affected males are always affected; hence the trait can be transmitted to offspring of both sexes. However, X-linked disorders do not always fit these rules.

X-linked dominant inheritance , sometimes referred to as X-linked dominance , is a mode of genetic inheritance by which a dominant gene is carried on the X chromosome. As an inheritance pattern, it is less common than the X-linked recessive type.

Sex-linked diseases are passed down through families through one of the X or Y chromosomes. X and Y are sex chromosomes. Dominant inheritance occurs when an abnormal gene from one parent causes disease, even though the matching gene from the other parent is normal. The abnormal gene dominates.

    X-linked recessive inheritance is a mode of inheritance in which a mutation in a gene on the X chromosome causes the phenotype to be expressed in males who are necessarily hemizygous for the gene mutation because they have one X and one Y chromosome and in females who are homozygous for the gene mutation, see zygosity.
