The document discusses genetic modification of foods and presents arguments on both sides of the issue. It begins with basic genetic principles and an overview of the human genome project. It then discusses single gene disorders and chromosome abnormalities. The rest of the document outlines eight arguments, four against genetically modified foods because they may cause allergies and lack labeling, and four in favor because they could reduce allergies, use less pesticides, and prevent crop failure. It concludes that genetic modification may not overall improve food supplies.
