In case of co-dominance/incomplete dominance 1`F_(1)` generation resembles both parents.

Explanation

### Step-by-Step Solution:

1. **Understanding Co-Dominance**:
- Co-dominance occurs when both alleles in a heterozygous organism contribute equally to the phenotype. This means that both traits are fully expressed.
- Example: In human blood groups, the A and B alleles are co-dominant. If an individual inherits one A allele (IA) and one B allele (IB), the resulting blood group is AB, which shows characteristics of both A and B blood types.

2. **Understanding Incomplete Dominance**:
- Incomplete dominance is a situation where one allele does not completely dominate the other, resulting in a phenotype that is a blend of the two traits.
