NEET MCQ Books for XIth & XIIth Physics, Chemistry & BiologyIn 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:
1. | Law of Segregation does not apply in this experiment. |
2. | This experiment does not follow the Principle of Dominance. |
3. | The pink colour in F1 is due to incomplete dominance. |
4. | Ratio of F2 is 1/4(red):2/4(pink):1/4(white). |

NEET MCQ Books for XIth & XIIth Physics, Chemistry & BiologyIn antirrhinum, two plants with pink flowers were hybridized. The F1 plants produced red, pink, and white flowers in the proportion of 1 red, 2 pink and 1 white. What could be the genotype of the two plants used for hybridization? Red flower colour is determined by RR, and White by rr genes.
