In class, we studied corn genetics and were observing corn kernel color (R = dark, r = light) and texture (S = smooth, s = wrinkled). In a dihybrid cross (The initial P generation has 2 true-breeding parental corns. F1 offspring are self-fertilized), what proportion of F2 offspring are expected to be dark and wrinkled?
