A cross between a red flower bearing plant and a white flower bearing plant of Antirrhinum produced all plants having pink flowers. Work out a cross to explain how this is possible.

Explanation

To explain how a cross between a red flower-bearing plant and a white flower-bearing plant of Antirrhinum (snapdragon) produces all plants with pink flowers, we need to delve into the concepts of genetics, specifically incomplete dominance. Here’s a step-by-step solution:

### Step 1: Define the Genotypes
- Let’s denote the red flower allele as **R** (dominant) and the white flower allele as **r** (recessive).
- The genotype of the red flower plant is **RR** (homozygous dominant).
- The genotype of the white flower plant is **rr** (homozygous recessive).

### Step 2: Perform the Cross
