How it works

Genetic Selection

Integration

Analyze DNA print and isolate beneficial gene

Traditional Breeding

Using viruses or Bacteria

Inter species crosses

We have become more dependent on GMOs than we think

Extract the beneficial gene to be transferred

Marker assisted selection

Injection with a fine needle

Purpose of GMOs

Genetic Modification

  • Increased resistance and resilience
  • Increased crop sizes
  • Increased nutrients
  • Increase success rate
  • Fight global warming
  • Manage growing population

Insert selected beneficial gene into DNA of organism being genetically modified

Mutation Breeding

Biolistics (biological ballistics) Particle mediated gene transfer

GMO Benefits

GMO Concerns

Conclusion

  • GMOs can solve the problem of feeding the growing population
  • GMOs can reduce the impact of climate change on food production
  • Can benefit developing countries
  • Reduce the use of Pesticides and Herbicides
  • Increase profit and success of farmers
  • Not enough information on side effects (belief that they increase the chances of getting cancer)
  • Could threaten balance of ecosystems
  • Not enough evidence proving health benefits
  • Center for Disease Control- Correlation between allergies in children under 18 and the use of GMOs

What are GMOs?

History

Gregor Mendel

Present day

GMOs are becoming a part of our evolving agriculture. They are a simple concept of technology that leads to many new possibilities, although there is still a lot of uncertainty about whether their benefits outweigh their threats or the other way around. GMOs have become a part of modern agriculture that we cannot change.
