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:
- AThis experiment does not follow the Principle of Dominance.
- BPink colour in F1 is due to incomplete dominance.
- CRatio of F2 is

(White) - DLaw of Segregation does not apply in this experiment
Solution & Step-by-step Explanation
Statement D is incorrect. The Law of Segregation applies to all instances of monohybrid inheritance. Even though the alleles show incomplete dominance (resulting in pink), the alleles themselves (R and r) remain distinct and segregate normally during gamete formation, resulting in the 1:2:1 ratio in F
