In Artirrhinum (Snapdragon), a red flower was crossed with a white flower and in F1 generation, pink flowers were obtained. When pink flower were selfed, the F2 generation showed white, red and pink flowers. Choose the incorrect statement from the following:
This experiment does not follow the Principle of Dominace
Pink colour in F1generation is due to incomplete dominace.
Ratio of F2 is (red): (Pink) : (white)
Law of Segregation does not apply in this experiment.
The frequency of recombination between gene pairs on the same chromosome as a measure of the distance between the genes was explained by:
