5b) Selective Breeding

Organisms are selectively bred to develop the best features:
Best features:

  • maximum yield of plants 
  • good health and disease resistance 
  • animals: fertility, not fatty, taste, docile (as pets) 
  • plants: attractive, nice smell, shape, fresh 
How to selective breed:
  1. Select organisms with desirable features (from existing stock) 
  2. Breed them with one another 
  3. Offspring: select the best of their offspring and breed them together
  4. Repeat the process- consistent organisms
