Two true-breeding pea plants are crossed. One parent is round,terminal, violet, constricted, while the other expresses the contrasting phenotypes of wrinkled, axial, white, full. The four pairs of contrasting traits are controlled by four genes, each located on a separate chromosome. In the F1 generation, only round, axial, violet, and full are expressed. In the F2 generation, all possible combinations of these traits are expressed in ratios consistent with Mendelian inheritance. Question: Which F2 phenotype is expected to occur least frequently? Write a mathematical expression that predicts this frequency.
