Question: the color of sunflower pollen can be orange yellow or...
The color of sunflower pollen can be orange, yellow, or white. Crosses reveal that true-breeding orange is dominant to both yellow and white. However, a cross between true-breeding white plants and true-breeding yellow plants produced F1 plants with orange pollen. After self-fertilization of these F1 plants, the F2 progeny were found to be in a ratio of 9 orange: 4 white: 3 yellow. What type of inheritance is suggested by these results?
