The Inheritance of a Somatic Variation in Maize 9 
centages. I have seen no report in which the detailed 
records were given. 
The diagram shows that a variegated branch of a varie- 
gated plant produces in F 1 mainly variegated plants, but 
occasionally a wholly green plant, while a green branch 
from the same plant produces in Fj 25 per cent, varie- 
gated and 75 per cent, green plants. The Fj variegated 
plants, however produced, behave in later generations 
just like the original variegated parent plant. The F 2 
green plants, whether produced from green or variegated 
branches, are always of two sorts, namely, those that are 
homozygous and therefore breed true green, and those 
that are heterozygous and therefore produce progenies of 
green and variegated individuals in a ratio of approxi- 
mately 3 to 1. Correns points out that a green branch of 
a variegated plant behaves as though it belonged not to a 
variegated plant at all, but to a hybrid between a varie- 
gated plant and a green one, in which green is dominant, 
and that half of the germ cells produced by the green 
branch carry a factor for green and the other half a factor 
for variegation. Similar results were secured from 
branches with self-colored flowers on plants with striped 
flowers, except that such branches produce few if any 
more self-colored plants than are produced by branches 
with striped flowers. Plants with self-colored flowers, no 
matter how they arise, behave as they would if they had 
occurred in an F 2 progeny of a cross of striped by self- 
colored plants. 
Eesults of Experiments with Maize 
Hartley 4 in 1902 gave an account of an experiment with 
variegated maize. In a comparatively pure white strain, 
which occasionally produced a red ear, there was found an 
ear similar to some of the " freak" ears noted earlier in 
this paper. It is described as being red except for a spot
