F2 generation: When the Punnett square is completed, we get three different genotypes in a 1:2:1 ratio: (Y-R)(Y-R), (Y-R)(y-r), and (y-r)(y-r). These genotypes correspond to a 3:1 ratio of yellow, round:green, wrinkled seeds. This is the prediction of the model in which the seed shape and seed color genes are completely linked.2. Draw a 2 x 2 grid. As its name suggests a Punnett square is just a divided square. Draw your square and divide it into four smaller squares by drawing two lines (one horizontal and one vertical) through the center of the square. Leave enough room in each box for two letters.As such, you expected 25 of the 100 students would achieve a grade 5. However, in reality, 30 students achieved a score of 5. As such, the chi-square calculation is as follows: X 2 = (30 - 25) 2 / 25 = (5) 2 / 25 = 25 / 25 = 1. An In-depth Example of the Chi-square Calculator.
