THE AMEBICAN NATURALIST [Vol. LIII 



The percentage of hulled kernels on the heterozygous 

 plants seem, to mdicate to some extent the percentage of 

 hulled kernels on the heterozygous offspring. 



No matter what percentage of hulled kernels is present 

 on the heterozygous individual, it tends in general to 

 produce a 1:2:1 ratio. 



The hulled and hull-less kernels from intermediate 

 plants reproduce similar 1:2:1 ratios.
