Selective Breeding
Controlling the way organisms breed for desired traits
Genetically Modified Organisms (GMOs)

Bt plants: insecticide, golden rice, flavr savr tomato
More GMOs
Cows engineered to produce HGH (Human Growth Hormone)
Nitrogen producing plants-decreased need for fertilizer
Controversy
Is it safe?Antibiotic resistanceNatural
populations/ecosystemGenetic modification of
animals & humans
Spiders + goats…
Canadian scientists combined spider DNA with the cells of lactating goats, they produced silk with their milk
That’s weird right?
Pros
Growing replacement organs for organ transplants
Preventing disease
Medical research: simulating human diseases
Gene Therapy
Introducing a healthy gene to replace a diseased gene in a human being.
Viral vector
Gene Therapy for Cystic Fibrosis
Jesse Gelsinger
Volunteered for experimental gene therapy in 1999
18 yrs old
Died a few days after from massive reaction to viruses
Cloning
How is it done?
What is wrong and what is right?
Ethics, where do we draw the line? Do we draw the line?
Is it safe?GMOs disrupting the balance of nature? I Am Legend Zombies?
