X-linked dominant disorder occurred due to genes present on the X-chromosomes.

X-Linked Dominant Inheritance

X-linked dominance is a mode of genetic inheritance by which a dominant gene is carried on the X-chromosome. 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 allele is sufficient to cause the disorder when inherited from the parent that has the disorder. In this, the abnormal gene dominates the gene pair....
