Detailed explanation-1: -A major concern of genetically modified organisms is that they will cause reduced genetic diversity of plants and animals in the environment. What this means is that the DNA, which codes for proteins in an organism, will become more similar between individuals of a species.

Detailed explanation-2: -It is even common for scientists to insert genes into an organism from an entirely different organism. This raises the possible risk of unexpected allergic reactions to some GMO foods. Other concerns include the possibility of the genetically engineered foreign DNA spreading to non-GMO plants and animals.

Detailed explanation-3: -Genetic modification produces genetically modified animals, plants and organisms. If they are introduced into the environment they can affect biodiversity. For example, existing species can be overrun by more dominant new species. These and other potential effects are considered during the licensing procedure.

Detailed explanation-4: -Potential health risks to humans include the possibility of exposure to new allergens in genetically modified foods, as well as the transfer of antibiotic-resistant genes to gut flora.

Detailed explanation-5: -It is known that the main concerns about adverse effects of GM foods on health are the transfer of antibiotic resistance, toxicity and allergenicity.
