Autosomal Dominant Trait

a. Usually appears in both sexes with equal frequency.

b. Both sexes transmit the trait to their offspring.

c. Does not skip generations.

d. Affected offspring must have an affected parent unless they possess a new mutation.

e. When one parent is affected (heterozygous) and the other parent is unaffected, approximately half of the offspring will be affected.

f. Unaffected parents do not transmit the trait.
