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:

Accepted Answer

The inheritance of flower colour in *Antirrhinum* (dog flower) is a classic example of Incomplete Dominance . In this cross, the F1 phenotype (pink) does not resemble either parent, indicating that the Principle of Dominance is not followed . However, the Law of Segregation still applies because the alleles separate during gamete formation, resulting in a genotypic ratio of 1 (RR) : 2 (Rr) : 1 (rr) in the F2 generation, which is exactly what is expected in any Mendelian monohybrid cross . Therefore, the statement that the Law of Segregation does not apply is incorrect.
