Final answer:
The F1 generation will have pink flowers as a result of the incomplete dominance between red and white flower colors. In the F2 generation, the genotypic ratio will be 1 CRCR:2 CRCW:1 CW CW, and the phenotypic ratio will be 1:2:1 for red:pink:white.
Step-by-step explanation:
The F1 generation of the cross between a white, tall, normal-flowered plant and a red, dwarf, symmetrical flowered plant will have pink flowers, as the red flower color is incompletely dominant to white. This is an example of incomplete dominance, where the heterozygote phenotype appears intermediate between the two parents. In the F2 generation, if the three gene pairs segregate independently, the genotypic ratio will be 1 CRCR:2 CRCW:1 CW CW, and the phenotypic ratio will be 1:2:1 for red:pink:white.
When the F1 generation is self-crossed to produce F2 progeny, we must calculate the phenotypic ratio for each trait separately due to independent assortment. For flower color, we expect a 1:2:1 phenotypic ratio (red:pink:white), whereas for the other traits, we observe a traditional 3:1 Mendelian ratio for dominant to recessive phenotypes because these traits follow complete dominance. The proportion of F2 plants that will resemble the F1 phenotype can be calculated by multiplying the probabilities of each individual trait expression.
