In snapdragons, flower color is often an example of incomplete dominance. When a red snapdragon (RR) is crossed with a white snapdragon (WW), the resulting offspring (RW) will have a pink flower color.
In this case:
- RR (red) x WW (white) → All RW (pink)
Therefore, when you cross a red snapdragon with a white snapdragon, 100% of the offspring will have pink flowers.
The probability of producing a pink flowered snapdragon is 1 (or 100%).
