Why genetically modified crops are made?
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 in fruit etc. less pronounced. For example, some crops may have a resistance to a certain disease that other crops do not have, the gene that causes the resistance to the disease can be introduced to another type of crop in order to create resistance in the other type of crop. Also some crops may have undesirable traits such as naturally occuring toxins which are a defence mechanism of the plant. Genetic modification can be used to stop the expression of the genes which cause these toxins to be produced, making crops safer for consumption.
