Final answer:

The offspring of two heterozygous red-flowering plants would result in both red-flowered and white-flowered plants.

Step-by-step explanation:

The offspring of two heterozygous red-flowering plants would result in both red-flowered and white-flowered plants. In this case, the red allele (r) is incompletely dominant over the white allele (r), leading to pink flowers in heterozygous offspring. The phenotype of the offspring is a blend of the two parents, with a genotypic ratio of 1:2:1 for red:pink:white flowers.

Since there is a color that dominants over another color, the red color should take the capital letter R and the white color should take the small letter r. Therefore, the heterozygous individual is symboled Rr. If crossing happened between Rr * Rr, the result will be both red flowered and white flowered with the ratio 3 red:1 white.
