With the help of one example each provide genetic explanation for the following observations: brgt (i)`F_1`-generation resembles both the parents.
`F_1`-generation does not resemble either of the parents

Explanation

To address the question regarding the genetic explanations for the two observations about the F1 generation, we can break down the response into two parts, each with a clear example.

### Step-by-Step Solution:

#### Observation 1: F1 generation resembles both parents
1. **Definition**: The F1 generation resembles both parents when both parents are homozygous for a trait.
2. **Example**: Consider a cross between two homozygous pea plants, one tall (TT) and one short (tt).
- **Parental Genotypes**:
