  for 
  instance, 
  the 
  dark 
  " 
  Mephisto 
  : 
  with 
  the 
  

   white-hearted 
  " 
  Danebrog," 
  the 
  hybrid 
  shows 
  

   the 
  active 
  character 
  of 
  the 
  dark 
  pattern. 
  

  

  Hairy 
  species 
  crossed 
  with 
  their 
  smooth 
  

   varieties 
  produce 
  hairy 
  hybrids, 
  as 
  in 
  some 
  

   wheats, 
  in 
  the 
  campion 
  (Lychnis), 
  in 
  Biscutetta 
  

   and 
  others. 
  The 
  same 
  holds 
  good 
  for 
  the 
  

   crosses 
  between 
  spiny 
  species 
  and 
  their 
  un- 
  

   armed 
  derivatives, 
  as 
  in 
  the 
  thorn-apple, 
  the 
  

   corn-crowfoot 
  (Ranunculus 
  arvensis) 
  and 
  

   others. 
  

  

  Lack 
  of 
  starch 
  in 
  seeds 
  is 
  observed 
  in 
  some 
  

   varieties 
  of 
  corn 
  and 
  of 
  peas. 
  When 
  such 
  de- 
  

   rivatives 
  are 
  crossed 
  with 
  ordinary 
  starch-pro- 
  

   ducing 
  types, 
  the 
  starch 
  prevails 
  in 
  the 
  hybrid. 
  

  

  It 
  would 
  take 
  too 
  much 
  time 
  to 
  give 
  further 
  

   examples. 
  But 
  there 
  is 
  still 
  one 
  point 
  which 
  

   should 
  be 
  insisted 
  upon. 
  It 
  is 
  not 
  the 
  systema- 
  

   tic 
  relation 
  of 
  the 
  two 
  parents 
  of 
  a 
  cross, 
  that 
  

   is 
  decisive, 
  but 
  only 
  the 
  occurrence 
  of 
  the 
  same 
  

   quality, 
  in 
  the 
  one 
  in 
  an 
  active, 
  and 
  in 
  the 
  other 
  

   in 
  an 
  inactive 
  condition. 
  Hence, 
  whenever 
  this 
  

   relation 
  occurs 
  between 
  the 
  parents 
  of 
  a 
  cross, 
  

   the 
  active 
  quality 
  prevails 
  in 
  the 
  hybrid, 
  even 
  

   when 
  the 
  parents 
  differ 
  from 
  each 
  other 
  in 
  

   other 
  respects 
  so 
  as 
  to 
  be 
  distinguished 
  as 
  sys- 
  

   tematic 
  species. 
  The 
  white 
  and 
  red 
  campions 
  

   give 
  a 
  red 
  hybrid, 
  the 
  black 
  and 
  pale 
  henbane 
  

   (Hyoscyamus 
  niger 
  and 
  H. 
  pallid 
  its) 
  give 
  a
