To achieve a 1:2:1 ratio of phenotypes for red, pink, and white flowers in Snapdragon plants, start by crossing RR (red-flowered plants) with rr (white-flowered plants). This initial cross ( 
x rr) will produce all 
offspring, which are pink due to incomplete dominance. In the next step, cross these 
(pink) offspring with each other ( 
). The resulting generation from this cross will display the genotype and phenotype ratios of 1 RR (red): 2 Rr (pink): 1 rr (white).
