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
