In a typical monohybrid cross the `F_(2)`-population ratio is written as `3:1` for phenotype but expressed as `1:2:1` for genotype. Explain with the help of an exmaple.

Explanation

To explain the difference between the phenotypic ratio of 3:1 and the genotypic ratio of 1:2:1 in a typical monohybrid cross, we can use the example of plant height in pea plants, where "T" represents the tall allele (dominant) and "t" represents the dwarf allele (recessive).

### Step-by-Step Solution:

1. **Identify the Parental Generation (P Generation)**:
- Let's consider a tall plant (TT) and a dwarf plant (tt).
- Parental Genotypes: Tall plant (TT) x Dwarf plant (tt)
