reproductive success and alleic frequency:

alleic frequency based upon reproductive success of indus.


  • organisms produce more offspring than can be supported by resources
  • competition betweeen members of species = survival of the fittest
  • gene pool has a wide variety of alleles
  • some indus possess alleles better suited to the particular env.
  • they will survive in competition with others
  • the ones that survive have a better change to breed more successfully
  • only those who reproduce successfully pass on alleles to next gen.
  • .: offspring more likely to inherit alleles
