  Considering

  cross 
  generation, 
  we 
  find 
  that 
  

   when 
  intermediate 
  kernels 
  were 
  planted 
  they 
  predominate 
  slightly 
  

   over 
  the 
  sweet. 
  The 
  proportions 
  are 
  from 
  intermediates:

  GENERAL 
  DISCUSSION 
  

   I. 
  Significance 
  of 
  the 
  intermediates 
  

  

  between 
  

  

  very 
  

  

  can 
  be 
  interpreted 
  as 
  a 
  separation 
  of 
  the 
  parental 
  germ 
  plasms 
  m 
  

   the 
  reduction 
  divisions 
  and 
  recombinations 
  of 
  the 
  gametes 
  so 
  

   produced 
  according 
  to 
  the 
  laws 
  of 
  chance 
  actually 
  occurs 
  as 
  East 
  

  

  cytologically 
  and 
  as- 
  

  

  It 
  is, 
  however, 
  equally 
  

  

  shown 
  

  

  sumed 
  eenerallv 
  in 
  Mendel 
  

  

  plain 
  that 
  provision 
  must 
  be 
  made 
  in 
  such 
  theoretic 
  conceptions 
  

   for 
  the 
  occurrence 
  of 
  intermediates. 
  There 
  is 
  evidence 
  of 
  segre- 
  

   gation 
  (chromosome 
  reduction) 
  but 
  not 
  of 
  the 
  so-called 
  punty 
  of 
  

   the 
  gametes. 
  We 
  

  

  accord 
  with 
  current 
  

  

  practice 
  factors 
  acting 
  as 
  modifiers, 
  inhibitors, 
  etc., 
  with 
  varying 
  

   efficiencies 
  in 
  the 
  case 
  of 
  different 
  kernels, 
  but 
  there 
  is 
  no 
  adequate
