What is Mendel's monohybrid ratio ?

Explanation

### Step-by-Step Solution:

1. **Understanding Monohybrid Cross**:
- A monohybrid cross involves a single trait or character. In Mendel's experiments, he focused on traits such as plant height (tall vs. short).

2. **Parental Generation (P Generation)**:
- Consider two parents: one homozygous tall plant (TT) and one homozygous short plant (tt).
- The tall plant has the genotype TT (dominant) and the short plant has the genotype tt (recessive).
