Since purple flowers are the Punnett Square most common feature, both have them. Because two heterozygous parents were crossbred, the F2 generation is more varied. The genotype distribution of the F2 generation is as follows: 50% heterozygous, 25% homozygous recessive, and 25% homozygous dominant.
The total number of boxes in your Punnett Square should be counted. You are then provided with the estimated total number of offspring. Subtract the (phenotype's prevalence in the generation ) from (the total number of offspring). To get your %, multiply the value from step 4 by 100.There are two homozygotic genotypes in the F2 generation that will breed successfully: GG and gg. However, only one of these two is yellow. Punnett Square, The correct response is 1/3 because only one of the three yellow seeds that were produced (GG, Gg, and gG) contains the genotype needed for proper breeding.
