Look at where the notes fall on the first three frets of the guitar, then the next five, and then the next four. The first string position being âopen,â the first four frets of the guitar neck are shown. The notes of the fourth through eighth frets.
The greatness of Mendeleev was that not only did he leave spaces for elements that were not yet discovered but he predicted properties of five of these elements and their compounds. How foolish he would have seemed if these predictions had been incorrect but fortunately for him three of these missing elements were discovered by others within 15 years (ie within his lifetime).
In other words, the contrasting parental traits were expected to blend in the offspring. Instead, Mendelâs results demonstrated that the white flower trait in the F 1 generation had completely disappeared. Importantly, Mendel did not stop his experimentation there. He allowed the F1 plants to self-fertilize and found that, of F2-generation plants, 705 had violet flowers and 224 had white flowers. This was a ratio of 3.15 violet flowers per one white flower, or approximately 3:1.
