An advantage is often higher crop yield. However they have also genetically modified plants to grow faster instead of more, or to produce better in a certain climate.

An advantage of genetically modified (GMO) crops was that less of the herbicide that the crop is resistant to is needed, meaning less pesticide residue may be present in harvested crops and in the environment. Unfortunately, that only seems to last a few years and then more of the pesticide is needed. For farmers, an advantage is that the pesticide can be sprayed on the crop directly.


The primary genetically modified crops grown in the US are soybean and maize. Rapeseed (used in canola oil) and cotton are also genetically modified.


The only proven disadvantage to genetically modified (GM) crops is that some people have shown an alleregic reaction.


It really depends what type of genetically modified crop it is


Genetically modified crops are crops with plants that have been genetically altered in order to increase the yield of the crop. For example, the plant may have been genetically altered to become bigger or more resistant to bugs.


Genetically Modified Crops have numerous advantages over the traditional varieties. Some of the advantages are: Genetically modified crops are disease resistant, insecticide resistant, pesticide resistant. They are better is taste and longevity. The fibres are adjusted to make eating smoother. They are modified to make them more nutritious.



No, because the crops are just grown faster than normal.


A lot of people are against genetically modified crops being grown because of potential negative health effects. The effects of altering crops genetically are also not known due to the process being relatively new.


genetically modified crops are those crops which are produced by the pollination of two species each with a unique feature to form a more resistable variety having more yield.


A genetically modified organism is a life form that has had its DNA code modified or changed. Genetically modified crops and farm animals are very common nowadays. When a gene from one organism is purposely moved to improve or change another organism in a laboratory, the result is a genetically modified organism (GMO).


In some cases, genetically modified organisms can make it easier to grow food. Some genetically engineered crops are able to grow better in certain areas than others. For instance, a genetically modified corn crop could be made to be better suited to growing in a certain environment than naturally occurring corn crops. These crops could be made so that they are more robust than natural crops, which could make them easier to grow. However, genetically modified crops could also cause problems, because they are not as genetically diverse as natural crops. This could be a problem if a disease breaks out among the crops. In populations of natural crops diversity allows some crops to survive such outbreaks because of genetic traits, but in genetically modified populations that diversity might not be present which could lead to the death of all the crops in a population and erasing the food supply.


1996 was the first year GMO crops were first grown commercially.


scientists dont completely understand genetics yet.



Genetically modified crops are made in order to make a desired trait, such as high yield, disease resistance, large fruit etc. more pronounced and/or undesired traits, such as toxins and large seeds...


They are genetically modified by controlling which ones reproduce. It is like a forced natural selection that is done by man in order to have desirable properties, like resistance to pesticides and herbicides.


It depends on how it has been modified and what traits were selected for modification. Generally they grow at a similar rate to non-modified crops.


Much of the corn and soybeans grown in Iowa are genetically modified (GM). Very little of any of the other crops have any significant modification done to them.


I assume you mean genetically modified, since anything that grows does so based on its genetic material. No, genetically modified crops do not take any longer to grow than their naturally-selected counterparts. When growing corn, for example, the farmer can choose from a fairly wide selection of maturity lengths, both in normal and in genetically modified.


There is no evidence that the development of genetically modified organisms helps to decrease the global food crisis, just as there is no evidence that GMO crops do anything toward that goal that the use of non GMO crops and/or organic crops could not do.


It was not discovered it was an invention. Crops have been genetically modified by selective cross breeding since before the start of recorded history. It is impossible to know who first attempted it.


GM crops do not necessarily have a greater or lesser yield than non-GMO crops.
