The color of sunflower pollen can be orange, yellow, or white-cream. Crosses reveal that true-breeding orange is dominant to both yellow and white-cream. However, a cross between true-breeding white-cream and yellow plants produced F1 plants with orange pollen. The F2 populations of this cross resulted in a ratio of nine orange: three yellow: four white-cream. If gene A is responsible for yellow color and gene B is responsible for white-cream color, match the phenotype with the appropriate genotype.
