Detailed explanation-1: -Herbicide resistant crops This reduces the quantity of herbicide that needs to be used. Potential disadvantages of this genetic modification include: the potential development of herbicide-resistant weeds. loss of biodiversity as fewer weed species survive as a food and shelter source for animals.
Detailed explanation-2: -Many crops such as tomatoes and corn are now routinely genetically manipulated to become more resistant to disease and herbicides. What is one disadvantage of this genetic resistance? The genes may be transferred to weeds during pollination.
Detailed explanation-3: -GM crops disrupt the natural process of gene flow because the “better” traits produced from engineering genes can result in the favouring of one organism. Cost of cultivation is increased. It endangers farmers and trade along with the environment. More items
