Question

In Antirrhinum (Snapdragon), a red flower was crossed with a white flower and in F1 generation pink flowers were obtained. When pink flowers were selfed, the F2 generation showed white, red and pink flowers. Choose the incorrect statement from the following : (A) Ratio of F2 is 1/4 (Red): 2/4(Pink): 1/4(White) (B) Law of Segregation does not apply in this experiment (C) This experiment does not follow the Principle of Dominance (D) Pink colour in F1 is due to incomplete dominance.

Genes for flower colour in snapdragon shows incomplete dominance which is an exception of Mendel's first principle i.e., Law of dominance. Whereas Law of segregation is universally applicable. So, the correct answer is 'This experiment does not follow the Principle of Dominance'

Q. 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 :

Ratio of F₂ is 1/4 (Red) : 2/4(Pink) : 1/4(White)

Law of Segregation does not apply in this experiment

This experiment does not follow the Principle of Dominance

Pink colour in F₁ is due to incomplete dominance.
