As the X chromosome is one of the [[sex chromosome]]s (the other being the [[Y chromosome]]), X-linked inheritance is determined by the [[sex]] of the parent carrying a specific gene and can often seem complex. This is due to the fact that, typically, [[female]]s have two copies of the X-chromosome, while [[male]]s have only one copy. The difference between [[Dominance (genetics)#Dominant trait|dominant]] and [[Dominance (genetics)#Recessive|recessive]] inheritance patterns also plays a role in determining the chances of a child inheriting an X-linked disorder from their parentage.{{fact|date=January 2018}}
