Solution

The pattern of inheritance shown in the scenario is A. Codominance. This is because in codominance, both alleles for a gene are fully expressed in the phenotype. In this case, the offspring plant has flowers that show both red and white colors, indicating that both the red and white flower color genes are being expressed simultaneously.
