From the angular yellow seeds 96 resulting plants bore seed, of which:
| 28 | had only angular yellow seeds | aB |
| 68 | angular yellow and green seeds | aBb. |
From 108 round green seeds 102 resulting plants fruited, of which:
| 35 | had only round green seeds | Ab |
| 67 | round and angular green seeds | Aab. |
The angular green seeds yielded 30 plants which bore seeds all of like character; they remained constant ab.
The offspring of the hybrids appeared therefore under nine different forms, some of them in very unequal numbers. When these are collected and co-ordinated we find:
| 38 | plants with the sign | AB |
| 35 | ❞❞❞ | Ab |
| 28 | ❞❞❞ | aB |
| 30 | ❞❞❞ | ab |
| 65 | ❞❞❞ | ABb |
| 68 | ❞❞❞ | aBb |
| 60 | ❞❞❞ | AaB |
| 67 | ❞❞❞ | Aab |
| 138 | ❞❞❞ | AaBb |
The whole of the forms may be classed into three essentially different groups. The first embraces those with the signs AB, Ab, aB, and ab: they possess only constant characters and do not vary again in the next generation. Each of these forms is represented on the average thirty-three times. The second group embraces the signs ABb, aBb, AaB, Aab: these are constant in one character and hybrid in another, and vary in the next generation only as regards the hybrid character. Each of these appears on
