Mendel did this with seven different character traits which were the color of the flower, the color of the seed, the shape of the seed, the shape of the pod, the color of the pod, the position of the flower and stem length. For example, for flower color, in Mendel's control group, Mendel had two sets of plants, one purple and the other white. Everything was the same between these plants except the color of the flowers. Mendel began his experiment by crossing a purple-flowered plant with a white-flowered plant, using pollen from the white-flowered plant on the purple-flowered plant. This was the P or parents generation. This cross produced plants with purple flowers. This new generation is called the F1 generation. Subsequently, he did the opposite and pollinated the white-flowered plants with pollen from the purple-flowered plants. Once again the result was plants with purple flowers. The results of this experiment first disproved the idea that if two colors are crossed, the offspring will show a color that is a mixture of the two. It also gave rise to the idea of ​​genetic dominance. Mendel wasn't sure then why there was no longer a trace of white in any of them
