X-Linked Dominant Traits

X-linked dominant traits affect both males and females. 

Although they often appear more frequently in females than in males.

Affected males must have affected mothers (unless the males possess a new mutation), and they pass the trait to all their daughters.

Affected daughters must have either an affected mother or an affected father.

X-linked dominant traits do not skip generations.
