Hybridization: crossing dissimilar individuals to bring together the best of both
Disease resistance to food-producing capacity
Inbreeding

3. Increasing Variation Polyploidy Many sets of chromosomes
Produce new species of plants that are larger and stronger
Fatal in animals

Restiction enzymes
Separating DNA
Gel electrophoresis

6. Transgenic Organisms
Contain genes from other species

7. Cloning
Member of a population of genetically identical cells produced from a single cell
