  From  Webster's  Revised  Unabridged  Dictionary  (1913)  [web1913]: 
 
  Reproduction  \Re`pro*duc"tion\  (-d?k"sh?n),  n.  [Cf.  F. 
  reproduction.] 
  1.  The  act  or  process  of  reproducing;  the  state  of  being 
  reproduced;  specifically  (Biol.),  the  process  by  which 
  plants  and  animals  give  rise  to  offspring. 
 
  Note:  There  are  two  distinct  methods  of  reproduction;  viz.: 
  {asexual  reproduction}  (agamogenesis)  and  {sexual 
  reproduction}  (gamogenesis).  In  both  cases  the  new 
  individual  is  developed  from  detached  portions  of  the 
  parent  organism.  In  asexual  reproduction  (gemmation, 
  fission,  etc.),  the  detached  portions  of  the  organism 
  develop  into  new  individuals  without  the  intervention 
  of  other  living  matter.  In  sexual  reproduction,  the 
  detached  portion,  which  is  always  a  single  cell,  called 
  the  female  germ  cell,  is  acted  upon  by  another  portion 
  of  living  matter,  the  male  germ  cell,  usually  from 
  another  organism,  and  in  the  fusion  of  the  two 
  (impregnation)  a  new  cell  is  formed,  from  the 
  development  of  which  arises  a  new  individual. 
 
  2.  That  which  is  reproduced. 
 
  From  WordNet  r  1.6  [wn]: 
 
  reproduction 
  n  1:  the  process  of  generating  offspring 
  2:  something  that  has  been  replicated  [syn:  {replica}] 
  3:  the  act  of  reproducing  [syn:  {replication}] 
  4:  the  activity  of  conceiving  and  bearing  offspring  [syn:  {procreation}, 
  {breeding}]
