Final answer:

The cross between two pink-flowered plants demonstrates incomplete dominance, producing a phenotypic ratio of 1:2:1 for red, pink, and white offspring.


Explanation:

Incomplete Dominance: This cross represents incomplete dominance, where neither allele is completely dominant resulting in a blend of traits. In this case, when pink-flowered plants are crossed, the offspring show a phenotypic ratio of 1:2:1 for red:pink:white.

Genotypic and Phenotypic Ratios: The genotypic ratio in this cross would be 1 CRCR:2 CCW:1 CW CW, illustrating the blending of alleles. The phenotypic ratio is 1:2:1 for red:pink:white coloration.
