WebTo make the square, we first put the four equally probable gamete types along each axis. Then, we join gametes on the axes in the boxes of the chart, representing fertilization events. The 16 16 equal-probability fertilization events that can occur among the gametes are shown in the 16 16 boxes. Web26 mrt. 2024 · To find the genotypic ratio, count the number of times each combination appears in the grid, starting in the upper left square. The example in Figure 1 below is crossing alleles for just one trait, flower color. Larger Punnett squares are used to calculate genotypic ratios for more than one trait as shown in Figure 2.
