Define the term co-dominance with one example.

Explanation

**Step-by-Step Text Solution:**

1. **Definition of Co-Dominance:**
Co-dominance is a genetic phenomenon where two different alleles for a trait are both expressed equally in the phenotype of an organism. This means that neither allele is recessive, and both contribute to the observable characteristics.

2. **Characteristics of Co-Dominance:**
- In co-dominance, both alleles in a heterozygous genotype manifest their effects in the phenotype.
- This results in a situation where the traits associated with both alleles are fully and simultaneously expressed.
