342174 In Antirrhinum (Snapdragon), a red flower was crossed with a white flower and in \({F_1}\) generation pink flowers were obtained. When pink flowers were selfed, the \({F_2}\) generation showed white, red and pink flowers. Choose the incorrect statement from the following :

1 This experiment does not follow the Principle of Dominance.
2 Pink colour in \({F_1}\) is due to incomplete dominance.
3 Ratio of \({F_2}\) is \(\frac{1}{4}\) (Red) \(:\;\;\frac{2}{4}\) (Pink) \(:\;\;\frac{1}{4}\) (White)
