Experiment 3 shows that even when cells are separated from their normal location and placed in a different area, they can still develop into the appropriate cell type. This suggests that a cell's fate is not irrevocably determined and can be influenced by its environment. Therefore, the normal embryo would not develop in Experiments 1 or 2, where cells were restricted to certain locations, but would develop in Experiment 3 where cells were allowed to move and differentiate based on their environment.
