1. Chapter 15: Genetic Engineering
Selective Breeding

2. What is Selective Breeding?
Breeding animals with desired traits for future generations
Examples:
Hybridization (Examples?)
Bringing different organisms together to bring out best traits
Allows for disease resistant organisms to be created
Inbreeding (Examples?)
Breeding organisms with similar characteristics
Problem: Genetic disorders occur after continual inbreeding

3. How can we increase genetic variation?
Biotechnology
Using technological processes or devices on living organisms
Examples:
Mutations
Radiation and chemicals to change bacteria
Drugs
Allow plants to keep extra chromosomes which make survival better

4. What is Recombinant DNA?
DNA created by combining DNA from different places
What are uses of it?
Allows scientists to change the genetic code of an organism
Brings in the idea of transgenics
Organisms with genes from other organisms
Clones
Creating an adult organisms from a single cell of another adult organism
First multicellular organism clones was Dolly the sheep in 1997

6. Agriculture and Industry
GM Crops
Genetically modified crops
Plants that have pesticides in them
Harmless to humans
Slows rotting and spoiling of plants
GM Animals
Genetically modified animals
Cows that have genes to help produced more milk
Growth hormones to create bigger animals with more meat
