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 was

crossbreeding

Reproduction by parents of different species or varieties of animals or

plants to produce hybrids

Then came

genetic engineering

Altering an organism’s genetic material through

adding, deleting, or changing segments of its

DNA…

…to produce desirable traits or to eliminate

undesirable ones

A process that enables transfer of genes

between different species which would not

interbreed in nature

Crossbreeding

Genetic Engineering

+ Slow Process+ Takes 15

years or more to produce

variable new crop variety+ Can only

combine traits from species

that are genetically

similar

+ Relatively faster process+ Usually costs

less+ Allows the insertion of genes from

almost any other organisms into

crop cells

Genetic Engineering somehow prevailed..

:(

And so, the birth of the Genetically

Modified Organism

GMO’s..

PROJECTED DISADVANTAGES PROJECTED ADVANTAGES

Need less fertilizer Irreversible and unpredictable genetic and ecological effectsNeed less water

More resistant to insects, disease, frost, and drought

Harmful toxins in food from possible plant cell mutations

Grow faster New allergens in food

Can grow in slightly salty soils Lower nutrition

May need less pesticides Increase in pesticide-resistant insects, herbicide-resistant weeds, and plant diseasesTolerate high levels of herbicides

Higher yields Can harm beneficial insects

Less spoilage Lower genetic diversity

According to The United Nations World Food

Programme (UN-WPF)…

There are several potential risks of GM food to Human Health, namely:

Direct health effects (toxicity);Tendencies to provoke allergic reaction;Specific components thought to have nutritional or toxic properties;

The stability of the inserted gene;Nutritional effects associated with genetic modification; andAny unintended effects which could result from the gene insertion.

Which two disadvantages and two advantages (of

GMF) do you think are the most important? Why?
