WebWe can confirm the link between the four types of gametes and the 9:3:3:1 9: 3: 3: 1 ratio using the Punnett square above. To 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. WebThe most common method of calculating the genotypic ratio is by making a Punnet square with zygotes derived from the F1 generation. In more complex cases as the number of alleles involved increases other methods such as the fork line method or the probability method can also be used.
