Genetic Engineering


	Genetic Engineering
	Advantages Can increase the yield of a crop, making more food GM crops can be engineered to contain the nutrients that are missing as people often lack nutrients in their diet in other countries. Eg,'golden rice' contains beta-carotene	Disadvantages Affects the number of weeds and flowers= the population of insects reducing the farmland biodiversity May develop allergies to the food Transplanted genes may get out into the natural environment eg herbicide resistance gene may be picked up by weed creating a 'super weed' variety.
	Evaluation

Can increase the yield of a crop, making more food
GM crops can be engineered to contain the nutrients that are missing as people often lack nutrients in their diet in other countries. Eg,'golden rice' contains beta-carotene

Affects the number of weeds and flowers= the population of insects reducing the farmland biodiversity
May develop allergies to the food
Transplanted genes may get out into the natural environment eg herbicide resistance gene may be picked up by weed creating a 'super weed' variety.
