multiple choice
mother only, not the father.
all answer choices are correct.
parent who does not exhibit the disease.
father only, not the mother.
mother or the father.

Explanation:

Autosomal dominant inheritance means that a single copy of the disease - causing allele (from either parent) is sufficient for a person to inherit the disorder. It is not restricted to only the mother or only the father. Also, a parent who does not exhibit the disease (assuming they do not have the dominant allele) cannot pass on the disease - causing allele in autosomal dominant inheritance.

Answer:

mother or the father.
