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.
Options
- AThe experiment does not follow the principle of dominance.
- BPink colour in F 1 is due to incomplete dominance.
- CRatio of F 2 is 1 4 (Red) : 2 4 (Pink) : 1 4 (White)
- DLaw of Segregation does not apply in this experiment.
Correct answer
D. Law of Segregation does not apply in this experiment.
Step-by-step solution
Law of Segregation: A pair of alleles for a pair of contrasting characters are brought together in a hybrid, they remain associated but not blend, and they segregate into gametes during gamete formation. This law is based on the fact that the two factors of a character present in an individual do not get mixed up (blending) and both the traits are recovered as such in the F 2 generation though one of these is not seen at the F 1 stage. During gametes or spore formation, factors of a pair separate or segregate from
