Why are `F_(2)` phenotypic and genotypic ratios same in a cross between red- flowered snapdragon and white-flowered snapdragon plants. Explain with the help of a cross.

Explanation

In Snapdragon when two types of pure breeding plants bearing red flower and white flower are crossed the `F_1` generation plants neither bear red nor while lower but beat pink flower exhibiting the incomplete dominance. The self breeding of pink flowering plants yields a progeny consisting of three types of plants: red. pink and white i.e.. 1 :2:1 both phenotypically and genotypically
