Figure 16-17 shows a dihybrid cross but it can be analyzed as a monohybrid cross of just smooth seed coat (S) and wrinkled seed coat (s) with complete dominance that should show a 1:2:1 ratio. Examine Figure 16-17 and see if you can find these results. Likewise, it can be analyzed as a monohybrid cross of yellow seed coat versus green. Can you find these in the expected ratio?
