Abstract

This review has focused on Impact of Gene Duplication on Genetically Modified Food Crops. Genetically modified crops (GMCs, GM crops, or biotech crops) are plants, the DNA of which has been modified using genetic engineering techniques. The aim is to introduce a new trait to the plant, which does not occur naturally in the species. Examples include resistance to certain pests, diseases, or environmental conditions, or resistance to chemical treatments (e.g. resistance to a herbicide), or the production of a certain nutrient or pharmaceutical agent. Gene duplication has had a significant impact on all genomes/ Food, as gene duplication contributes much of the raw material for natural selection to shape novel genes. In the context of crops evolution, interest in gene duplication has been intense as the crops genome is particularly rich in duplicated genomic regions. These duplicate genes contribute to genomic instability, leading to genome rearrangement and speciation. Recent evidence suggests that duplicated genes have undergone greater diversification than other loci in the corps.
