A trait is best defined as:
AA single chromosome from one parent
BA protein produced by an active gene
CA variation in a heritable characteristic
DA permanent change in a DNA sequence

3. A trait is defined as a variation in the physical appearance of a heritable characteristic.
4. A DNA change is a mutation, which may or may not alter a trait.
