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. IN medicine, X-linked dominant inheritance indicates that a gene responsible for a genetic disorder is located on the X chromosome, and only one copy of the gene is sufficient to cause the disorder when inherited from a parent who has the disorder. AS the X chromosome is one of the sex chromosomes (the other being the Y chromosome), X-linked inheritance is determined by the gender of the parent carrying a specific gene and can often seem complex. THis is due to the fact that, typically, females have two copies of the X-chromosome, while males have only one copy.
