What are genetically modified crops explain with examples?

What are genetically modified crops explain with examples?

Genetically modified crops / biotech crops are crops used used in agriculture , the DNA of which has been modified using external genes . crops in which genetic material is been artificially altered to produce a new species. for example :-alfalfa , sugar beet , maize etc.

What are genetically modified crops answer?

GM crops are plants that have been modified, using genetic engineering, to alter their DNA sequences to provide some beneficial trait. For example, genetic engineering can improve crop yield, resulting in greater production of the target crop.

What are genetically modified crops Class 9?

Answer: Crops which are been developed by introducing a new gene from any other source, e.g., bacteria or any other organism to obtain the desired character is called Genetically Modified (GM) crop. Bt cotton is an example of GM crop which is made insect-resistant by introducing a new gene from a bacteria.

What is the purpose of genetically modified crops?

Most of the GMO crops grown today were developed to help farmers prevent crop loss. The three most common traits found in GMO crops are: Resistance to insect damage. Tolerance to herbicides.

How many crops are genetically modified?

In the United States there are 11 commercially available genetically modified crops in the United States: soybeans, corn (field and sweet), canola, cotton, alfalfa, sugar beets, summer squash, papaya, apples and potatoes.

What are examples of genetically modified foods?

Most Common GMOs

  • Alfalfa. Much of commercially available alfalfa has been genetically modified to contain a gene that makes it resistant to the herbicide Roundup.
  • Canola. It is estimated that about 90% of US canola crops are genetically modified.
  • Corn.
  • Cotton.
  • Papaya.
  • Potato.
  • Soy.
  • Sugar Beet.

What are the disadvantages of genetically modified crops?

Perceived disadvantages of genetically modified crops may be grouped into five categories: 1) potential impact on non-target species; 2) potential for increased weediness; 3) increase in toxin levels in the soil; 4) exchange of genetic material between the transgenic crop and related plant species; and 5) selection for …

What are genetically modified crops Class 8?

Genetically modified crops are the crops whose genes are modified using genetic engineering techniques. These are also called transgenic crops. The main goal of producing GMOs is to increase the yield of the crop and to produce disease-resistant crops.
