How genetic engineering of plants and animals can be both beneficial and harmful to the environment and to people

 plants:

(1.Less use of pesticides

2. Increased supply of food with reduced cost and longer shelf life

3. Faster growing plants and animals) = benefits

(1.Creating foods that can cause an allergic reaction or that are toxic

2.Unexpected or harmful genetic changes

3.Genes moving from one GM plant or animal to another plant or animal that is not genetically engineered) = harm

animals:

The benefits include advancing human health, enhancing food production, reducing environmental impact, optimizing animal health and welfare and production of cutting edge industrial applications.

the harmful reason of animal genetic engineering is that it coukld bring a slight disturbance to the ecosystem with the other animals

Explanation:

the offspring would all be white. if the parents are both white flowers then they have the genotype rr, which when crossed results in an all white punnet square.
