Answer:
Answer
Such a condition in which both the genotypic and phenotypic ratios are same is an example of incomplete dominance. In snapdragon plants (Antirrhinum), a cross between a red flowered (RR) plant and a white flowered plant (rr) results in all F1 generation plants being pink flowered (Rr), an intermediate phenotype. When a cross is carried out between two pink flowered plants, it results in an F2 generation where red, pink and white flowers are seen in the ratio of 1:2:1. They have a genotypic ratio of RR (Red): Rr (pink): rr(white) that is equal to 1:2:1. So, both the phenotypic and the genotypic ratios are same.
