A particular flower can be purple, blue, red or white. Two purple F1 plants are crossed to produce an F2 generation. Might a 9:3:3:1 phenotypic ratio in the F2 indicate? A) additive allelic interactions B) recessive reciprocal epistasis allelic interactions C) dominant epistasis allelic interactions D) Redundant gene interactions
