Give the genotypic and phenotypic ratio of `F_(1)`, generation,when a hybrid tall (Tt) pea plant is crossed with a pure dwarf (tt)pea plant.

Explanation

To solve the problem of determining the genotypic and phenotypic ratios of the F1 generation when a hybrid tall pea plant (Tt) is crossed with a pure dwarf pea plant (tt), we can follow these steps:

### Step 1: Identify the Parent Genotypes
- The hybrid tall pea plant has the genotype Tt (where T = tall and t = dwarf).
- The pure dwarf pea plant has the genotype tt.

### Step 2: Determine the Gametes Produced by Each Parent
- The hybrid tall plant (Tt) can produce two types of gametes: T (tall) and t (dwarf).
