This increase in glyphosate-resistant crops has led to an increase in herbicide use, herbicide-resistant weeds (also known as "superweeds"), and numerous other environmental and human health impacts. Genetic transformation is an essential step in genetic engineering of higher plants because: Select one: a. tumorous callus tissue must be maintained for every genetically modified species. Herbicide resistance in weeds, like herbicide fate, constitutes a broad branch of research involving herbicides and is beyond the scope of this article - but it is also the basis for its organization.

Similarly, a cow can only mate with another cow. Peter Griffiths Aviation, Other common traits include virus resistance, delayed ripening, modified flower colour or altered composition. Although research into herbicides began in the early 20th century, the first major breakthrough was the result of research conducted in both the United Kingdom and the United States during the Second World War into the potential use of herbicides in war. Herbicide resistance is the inherited ability of a plant to survive and reproduce following exposure to a dose of herbicide that would normally be lethal to the wild plant.

A genetically modified organism (GMO) is an animal, plant, or microbe whose DNA has been altered using genetic engineering techniques. However, the downside of herbicide use on GM crops is that when agriculturalists use the same pest management tactic for years, they start to see pests (such as weeds) that are resistant.
