1.

There are several concerns being raised in accepting transgenic crops. List any three of them.

Answer»

1. The safety of GM food for human and animal consumption (e.g. GM food may cause allergenicity).

2. The effect of GM crops on biodiversity and environment. The effect of GM crops on non-target and beneficial insects/microbes. 

3. Transgenes may escape through pollen to related plant species (gene pollution) and may lead to the development of super weeds.

4. The GM crops may change the fundamental vegetable nature of plants as the genes from animals (e.g. fish or mouse) are being introduced into crop plants.

5. The antibiotic resistance marker genes used to produce transgenic crops may horizontally transfer into microbes and thus exacerbate problem of antibiotic resistance in human and animal pathogens (i.e. transgenes may move from plants to gut microflora of humans and animals).

6. The GM crops may lead to the change in the evolutionary pattern.
