Question

Genetically modified grass varieties that carry genes for disease and drought resistance are now available. They were produced by recombinant DNA technology. However, the government has still not approved the sale of most of them, due to cautionary factors. What is the main reason for this concern?

Answer 1

Ans.

Genetically modified grasses are produced by using genetic engineering techniques, which contain genes for drought and disease resistance. Due to those genes, these grass varieties have higher chances to survive in stress condition and they spread with a fast and tremendous rate.

Most of the genetically modified grass varieties are still not approved by government, because 'these grass species may act as uncontrolled invasive species and cause harm to other useful plant species as they can spread fast and hard to wipe out due to resistance against stress conditions.'
