  half 
  wholly 
  red. 
  Four 
  individuals 
  were 
  found 
  

   with 
  only 
  uniform 
  red 
  flowers. 
  These 
  were 
  iso- 
  

   lated 
  and 
  artificially 
  pollinated, 
  and 
  the 
  same 
  

   was 
  done 
  with 
  some 
  of 
  the 
  best 
  striped 
  indi- 
  

   viduals. 
  The 
  seeds 
  from 
  every 
  parent 
  were 
  

   sown 
  separately, 
  so 
  as 
  to 
  allow 
  the 
  determina- 
  

   tion 
  of 
  the 
  proportion 
  of 
  uniform 
  red 
  individ- 
  

   uals 
  in 
  the 
  progeny. 
  

  

  Neither 
  group 
  was 
  constant 
  in 
  its 
  off- 
  

   spring. 
  But 
  as 
  might 
  be 
  expected, 
  the 
  type 
  

   of 
  the 
  parent 
  plant 
  prevailed 
  in 
  both 
  groups, 
  

   and 
  more 
  strongly 
  so 
  in 
  the 
  instances 
  with 
  

   the 
  striped, 
  than 
  with 
  the 
  red 
  ones. 
  Or, 
  in 
  

   other 
  words 
  seed-reversions 
  were 
  more 
  numer- 
  

   ous 
  among 
  the 
  already 
  reverted 
  reds 
  than 
  

   among 
  the 
  striped 
  type 
  itself. 
  I 
  counted 
  2% 
  

   reversion 
  in 
  the 
  latter 
  case, 
  but 
  24% 
  from 
  the 
  

   red 
  parents. 
  

  

  Among 
  the 
  striped 
  plants 
  from 
  the 
  striped 
  

   parents, 
  I 
  found 
  some 
  that 
  produced 
  bud- 
  

   variations. 
  I 
  succeeded 
  in 
  isolating 
  these 
  red 
  

   flowering 
  branches 
  in 
  paper 
  bags 
  and 
  in 
  polli- 
  

   nating 
  them 
  with 
  their 
  own 
  pollen, 
  and 
  subjected 
  

   the 
  striped 
  spikes 
  of 
  the 
  same 
  individuals 
  to 
  a 
  

   similar 
  treatment. 
  Three 
  individuals 
  gave 
  a 
  

   sufficient 
  harvest 
  from 
  both 
  types, 
  and 
  these 
  

   six 
  lots 
  of 
  seeds 
  were 
  sown 
  separately. 
  The 
  

   striped 
  flowers 
  repeated 
  their 
  character 
  in 
  98$ 
  

   of 
  their 
  offspring, 
  the 
  red 
  twigs 
  in 
  only 
  71$, 
  the
