In Antirrhinum (Snapdragon), a red flower was crossed with a white flower and in ${\text{F}}_1$ generation all pink flowers were obtained. When pink flowers were selfed, the ${\text{F}}_2$ generation showed white, red and pink flowers. Choose the incorrect statements from the following.

Law of segregation is universal. There is no exception to this law.

As the dominant colour is not expressed in  ${\text{F}}_1$ generation we can say that the principle of dominance is not followed.

An intermediate phenotype is expressed in ${\text{F}}_1$ generation which is because of incomplete dominance.

When we do selfing of ${\text{F}}_1$ generation the genotypic ratio of  ${\text{F}}_2$ generation is 1 /4 RR, 2/4 Rr, 1 /4 rr.
