Genetically modified food Genetically modified food Presentation Transcript

  • HOAX OR NOT?
  • Amphibious Tuber?
  • Supah Chicken!?
  • Anna Banana?
  • Genetically Modified Food
  • WHAT TO EXPECT Differentiate Genetic Engineering from Crossbreeding Describe a Genetically Modified Food Identify the risks and benefits of genetically modified food Assess the Desirability Quotient of GMF
  • Before, it wascrossbreeding
  • Reproduction by parents ofdifferent species or varieties of animals or plants to produce hybrids
  • Then came geneticengineering
  • Altering an organism’s genetic material throughadding, deleting, or changing segments of its DNA…
  • …to produce desirable traitsor to eliminate undesirable ones
  • A process that enablestransfer of genes between different species which would not interbreed in nature
  • CrossbreedingThink-Pair-Share vs. Genetic Engineering
  • + Slow Process+ Takes 15 years + Relatively faster or more to processproduce variable + Usually costs lessnew crop variety + Allows the + Can only insertion of genes combine traits from almost anyfrom species that other organisms are genetically into crop cells similar
  • Genetic Engineeringsomehow prevailed.. :(
  • And so, the birth of the GeneticallyModified Organism
  • GMO’s..crops and food
  • 1. What reason has caused major corn production loss as shown in the video?2. What is BT Corn? Where Think-Pair-Share Size 4 | SW did it come from?3. What actions were taken during the time when most farmers showed dis
  • Organisms in which geneticmaterial has been altered in a way that does not occur naturally
  • PROJECTED DISADVANTAGES PROJECTED ADVANTAGESNeed less fertilizer Irreversible and unpredictableNeed less water genetic and ecological effectsMore resistant to insects, disease, Harmful toxins in food fromfrost, and drought possible plant cell mutationsGrow faster New allergens in foodCan grow in slightly salty soils Lower nutritionMay need less pesticides Increase in pesticide-resistant insects, herbicide-resistantTolerate high levels of herbicides weeds, and plant diseasesHigher yields Can harm beneficial insectsLess spoilage Lower genetic diversity
  • According to The United Nations World FoodProgramme (UN-WPF)…
  • According to The United Nations World FoodProgramme (UN-WPF)…
  • There are several potentialrisks of GM food to Human Health, namely:
  • Direct health effects (toxicity);Tendencies to provoke allergicreaction;Specific components thoughtto have nutritional or toxicproperties;
  • The stability of the insertedgene;Nutritional effects associatedwith genetic modification; andAny unintended effects whichcould result from the geneinsertion.
  • Which two disadvantages and two advantages (ofGMF) do you think are the most important? Why?
