Q.
In Antirrhinum (Snapdragon), a red flower was crossed with a white flower and in $F_{1}$ generation all pink flowers were obtained. When pink flowers were selfed, the $F_{2}$ generation showed white, red and pink flowers. Choose the incorrect statements from the following. [2019]

1 Law of segregation does not apply in this experiment.

2 This experiment does not follow the Principle of Dominance.

3 Pink colour in $F_{1}$ is due to incomplete dominance.

4 Ratio of $F_{2}$ is $\frac{1}{4}$ (red) : $\frac{2}{4}$ (pink) : $\frac{1}{4}$ (white)

Ans.
(1)

Law of segregation applies in this case as when pink flowers obtained in $F_{1}$ are selfed then red and white flowers are obtained in $F_{2}$ which indicates that there is no mixing of gametes.
