Differentiate between codominance and dominance.

Explanation

To differentiate between codominance and dominance, we can follow these steps:

### Step-by-Step Solution:

1. **Definition of Dominance**:

- Example: In pea plants, the allele for tall plants (T) is dominant over the allele for short plants (t). Therefore, a plant with genotype Tt will be tall.
