A particular flower can be purple, blue, red or white. Two different pure-breeding white plants are crossed and the F1 are then crossed to produce an F2 generation. What might a 9:7 phenotypic ratio in the F2 indicate? A) additivity B) codominance C) recessive lethality D) reciprocal recessive epistasis E) dominant epistasis Explain each answer.
