From this it is perceived that, according to the above theory, in the third year of the experiment out of all the plants
| Half should have | violet-red flowers (Aa), | Classes | 1, 3 |
| ❞❞❞ | white flowers (a) | ❞ | 2, 4 |
| ❞❞❞ | a long axis (Bb) | ❞ | 1, 2 |
| ❞❞❞ | a short axis (b) | ❞ | 3, 4 |
From 45 fertilisations of the second year 187 seeds resulted, of which only 166 reached the flowering stage in the third year. Among these the separate classes appeared in the numbers following:—
| Class. | Colour of flower. | Stem. | ||
| 1 | violet-red | long | 47 | times |
| 2 | white | long | 40 | ❞ |
| 3 | violet-red | short | 38 | ❞ |
| 4 | white | short | 41 | ❞ |
There consequently appeared—
| The | violet-red | flower colour | (Aa) | in 85 | plants. | |
| ❞ | white | ❞❞ | (a) | in 81 | ❞ | |
| ❞ | long | stem | (Bb) | in 87 | ❞ | |
| ❞ | short | ❞ | (b) | in 79 | ❞ | |
The theory adduced is therefore satisfactorily confirmed in this experiment also.
For the characters of form of pod, colour of pod, and position of flowers experiments were also made on a small scale, and results obtained in perfect agreement. All combinations which were possible through the union of the differentiating characters duly appeared, and in nearly equal numbers.
Experimentally, therefore, the theory is justified that the pea hybrids form egg and pollen cells which, in their
