WebMendel’s experiments extended beyond the F 2 generation to the F 3 generation, F 4 generation, and so on, but it was the ratio of characteristics in the P, F 1, and F 2 generations that were the most intriguing and became the basis of Mendel’s postulates. Figure 8.3 Mendel’s process for performing crosses included examining flower color. WebA true experiment is defined as an experiment conducted where an effort is made to impose control over all other variables except the one under study. It is often easier to impose this sort of control in a laboratory setting. Thus, true experiments have often been erroneously identified as laboratory studies.
