WebOf the 315 round and yellow seeds planted, 301 plants matured and produced seed. The seed produced was the F3 generation. At harvest, Mendel needed to exercise the utmost care. Each F2 plant was handled separately. The seeds from the plant were harvested and Mendel then scored the F3 seeds that came from the same F2 plant. WebConduct. The data in Figure 2.5 show the results of the F 2 generation for seven of Mendel’s crosses. Conduct a chi square analysis to determine if these data are consistent with the law of segregation.
