the hybrids.
For each of these four experiments the whole of the flowers on three plants were fertilised. If the above theory be correct, there must be developed on the hybrids egg and pollen cells of the forms AB, Ab, aB, ab, and there would be combined:—
1. The egg cells AB, Ab, aB, ab with the pollen cells AB.
2. The egg cells AB, Ab, aB, ab with the pollen cells ab.
3. The egg cells AB with the pollen cells AB, Ab, aB, ab.
4. The egg cells ab with the pollen cells AB, Ab, aB, ab.
From each of these experiments there could then result only the following forms:—
