In snapdragons, red flower color (R) is incomplete dominant with white (W), the heterozygotes being pink; the normal (broad) leaves (B) are incomplete dominant with narrow (grass like) leaves (N), the heterozygotes having leaves of medium breadth. If a red-flowered, broad-leaved plant is crossed with a white-flowered, narrow-leaved one, (a) what will be the phenotypes and their expected ratio in the F1 generation? (b) If two F1 generation flowers are crossed, what is the phenotype and expected ratio is the F2 generation?
