Figure 8.2.1 A Punnett square shows the production of the F2 generation in a typical dihybrid cross, looking at the seed colour and seed shape of a particular plant. Crossing the two heterozygotes in the F1 generation produces offspring in the F2 generation in the typical 9:3:3:1 ratio. [Back to Figure 8.2.1]STEP 3: Set up a Punnett Square. In introducing dihybrid crosses, we used a Punnett square which was 4 squares x 4 squares, to accommodate all the possible gametes.
