X-Linked Dominant

X-Linked Dominant Definition

X-linked dominant is a mode of inheritance where a gene on the X-chromosome is dominant. It is a mode that is less common to the X-linked recessive and unlike males, females are said to be more affected than males inasmuch as females have two x Chromosomes which may be a potential carrier of the abnormal gene. Theory suggests that a woman with a disorder that is passed through a X-link dominant mode has a 50% chance of affecting the child while the daughter of a man with a disorder characterized by an X-linked dominant will inherit the said condition. However, the chance of passing the disorder that is said to be an X-linked disorder varies between men and women.
