  Six 
  ears 
  consisted 
  largely 
  of 
  pure 
  starchy 
  

   kernels 
  with 
  few 
  intermediates.

  The

  about

  Sixteen 
  ears 
  gave 
  both 
  starchy 
  and 
  sweet 
  kernels 
  and 
  would 
  be 
  

   classed 
  as 
  hybrids. 
  The 
  number 
  of 
  starch}' 
  intermediate 
  and 
  

   sweet 
  kernels 
  for 
  each 
  of 
  these 
  ears 
  is 
  given 
  in 
  Table 
  II, 
  section 
  3, 
  

   A, 
  &. 
  For 
  the 
  whole 
  series 
  of 
  sixteen 
  ears 
  there 
  is 
  a 
  proportion 
  of 
  

   one 
  intermediate 
  to 
  ninety 
  sweet 
  and 
  starchy 
  taken 
  together. 
  

   If 
  we 
  divide 
  the 
  intermediates, 
  putting 
  half 
  of 
  them 
  with 
  the 
  

   starchy 
  and 
  half 
  with 
  the 
  sweet 
  kernels, 
  we 
  have 
  1981.5 
  starchy 
  

   to 
  660.5 
  sweet 
  kernels 
  an 
  exact 
  3:1 
  ratio. 
  Assuming 
  that 
  the 
  

   differences 
  in 
  wrinkling 
  and 
  translucency 
  are 
  really 
  negligible 
  and 
  

   that 
  some 
  of 
  the 
  intermediates 
  really 
  belong 
  with 
  each 
  of 
  the 
  two 
  

   starchy 
  sweet 
  classes, 
  such 
  results 
  as 
  these 
  and 
  the 
  preceding 
  have 
  

   been 
  generally 
  regarded 
  as 
  evidence 
  of 
  so-called 
  purity 
  of 
  stock, 
  

   homozygosity.
