Answer:

The ratios would be 3 red to 1 pink for the genotypic ratio, and the phenotypic ratio would be 3 red flowers to 1 pink flower.

Explanation:

First, the red four o'clock flower and the pink four o'clock flower would be crossed. This would produce offspring that would have a genotypic ratio of 3 red to 1 pink. This means that for every 4 offspring, 3 would have the genes for red flowers, and 1 would have the genes for pink flowers. However, the phenotypic ratio would be different. This is because the phenotype is determined by the dominant gene. In this case, the red gene is dominant, so the phenotypic ratio would be 3 red flowers to 1 pink flower.
