GMO:
•Higher crop yields •Reduced need for herbicides and pesticides •Improved food quality •Increased nutritional value Cons •Possible allergies •Unpredicted changes to the ecosystem •Chance of new diseases developing SELECTIVE BREEDING AND ANIMAL HUSBANDRY
We choose the characteristics we want:
SELECTIVE BREEDING PROCESS: •Decide which characteristics are important •Choose parents that show these characteristics •Select the best offspring from parents to breed the next generation •Repeat the process continuously • •Human controlled Natural Selection/Evolution GENE THERAPY: Reasons for Gene Therapy: •To alter genes to correct genetic defects •prevent or cure genetic diseases. •Not to be confused with Genetic engineering which changes the genes to make the organism better than normal. •Possibility to cure deadly diseases like cancer Process for Gene Therapy: Three different ways: •Replacing a mutated gene that causes disease with a healthy copy of the gene •Inactivating, or “knocking out,” a mutated gene that is functioning improperly •Introducing a new gene into the body to help fight a disease •Pros: •Could wipe out genetic diseases •Prevent genetic disorders in future generations for families who know they have it in their bloodline •Cons: •Still a dangerous and difficult process •When used in unborn children, not sure of effects •Child doesn’t have a choice Comments are closed.
