X-Linked Dominant Trait

a. Both males and females are usually affected; often, more females than males are affected.

b. Does not skip generations. Affected sons must have an affected mother; affected daughters must have either an affected mother or an affected father.

c. Affected fathers pass the trait to all their daughters.

d. Affected mothers (if heterozygous) pass the trait to half of their sons and half of their daughters.
