Question

Quizplus · Accepted Answer

X-linked diseases are caused by mutations on genes found on the X chromosome. Females have two X chromosomes while males have only one X chromosome and one Y chromosome. This means that males are more likely to inherit X-linked diseases because they do not have a second X chromosome to compensate for the mutation. Females, on the other hand, can inherit an X-linked disease if they have a mutation on both their X chromosomes or if their father has the mutation and their mother is a carrier. However, the majority of individuals with X-linked diseases are male.
