What are the phenotypes of the F1 generation snapdragons?

The phenotypes of snapdragons of F1 generation had pink flowers only.

Explanation:

The crossing of snapdragon with red flowers and white flowers as well led to the production of F1 offspring of hybrid quality having pink flowers only. This F1 phenotype under goes pollination and results in F2 phenotype with a ratio of 1 red, 1 white and 2 pink flower.

This is incomplete dominance as the phenotypes of parental plant, as in the white and red flowered plant reappear in the F2 generation.
