The Inheritance of a Somatic Variation in Maize 19 
cases as if they were hybrids between red-eared and 
white-eared races. 
Of the four possible sorts of red-eared " sports' ' from 
variegated-eared plants, two remain to be treated. Be- 
cause of their similar behavior they will be considered 
together here. Of the F x red ears arising from homozy- 
gous, variegated-eared plants that had been crossed with 
white-eared races, three were self-pollinated and two 
crossed with whites. Of the F a red ears arising from 
heterozygous, variegated- eared plants that had been 
crossed with white-eared races, four were selfed. The 
results in F 2 and F 3 are :

So far as these results go they indicate that F ± reds 
arising from crosses between both homozygous and heter- 
ozygous, variegated-eared plants and white-eared races 
behave as if they were hybrids between red-eared and 
white-eared races. 
One homozygous, variegated-eared plant was cross- 
pollinated by a homozygous red race. From the varie- 
gated ear produced, self-red, nearly self-red, and narrow- 
striped seeds were planted. All resulted, of course, in 
red-eared Fj plants, 16 in all. A self-pollinated F x red 
ear from a narrow-striped seed gave in F 2 24 red-eared 
and 11 variegated-eared plants — somewhat fewer reds 
than were to have been expected. An F x red ear from a 
nearly self-red grain, when cross-pollinated with non-red, 
yielded 9 reds and 11 variegated in F 2 . A third Fi red-
