Genetically modified plants

Genes are in everything that lives. They are a code that oversees how living things appear and what characteristics they have. Genetic modification changes the genes and in doing so, also changes the characteristics of the subject. A plant is genetically modified when a scientist inserts a different gene from another species into the plant’s own gene. It is possible to transfer genes from one species to another because all genes are created from the same material.

Some benefits from genetic modification include more nutritious and tastier food, increased food supply, faster growing plants, and plants at are more resistant to pests and diseases. Some risks that are included in genetic modification are genetic changes that are unexpected and harmful, interbreeding which can cause extinction, and plants could be less resistant to some pests and more to others. There is still a lot of unknown knowledge regarding the safety of genetic modification. Once a genetically modified plant or crop has been released into the environment, there is no way to stop it from reproducing and polluting the Earth.

Some main issues that are a worry for human health when dealing with genetic modification are provoking allergic reactions (allergenicity), outcrossing, and gene transfer. People have raised concerns that genes from one food that are injected into another could cause allergic reactions. Such as if peanut genes are injected into a tomato, someone with a peanut allergy could react when eating that tomato. No allergic effects have yet been found in relation to genetically modified foods that are currently on the market. Outcrossing is the movement of genes from a genetically modified plant put into an ordinary plant, as well as the mixing of the seeds from an ordinary plant with a genetically modified plant. This could have an unintended effect on food safety. This risk was shown when traces of a maize type, which was only approved for...
