Suppose that tall plants are crossed with short, and the progeny are medium height.The F₁ plants are then crossed, and the progeny among the F₂ have many more size classes (9) than what is typically seen in crosses involving a single gene (fewer than 4).Which is the best explanation for this outcome? A) The existence of pleiotropic alleles B) Incomplete dominance C) Codominance D) Epistasis E) Multiple alleles
