genetically modified organism
Genetically modified crops are assessed for their impact on environmental factors such as soil quality.
The primary difference between genetically modified organisms (GMOs) and organisms produced through selective breeding lies in the methods used to alter their genetic makeup.
- Selective Breeding: This is a traditional, long-standing practice where humans intentionally mate individuals of a species that possess desirable traits to increase the frequency of those traits in future generations. It relies on natural reproductive processes and the inheritance of existing genetic variations within a species.12
- Genetic Modification: This involves the use of sophisticated recombinant DNA technology and other laboratory techniques to precisely alter an organism's genome at the molecular level. Unlike selective breeding, genetic engineering often allows for the insertion of genes from unrelated species to express traits that would be difficult or impossible to achieve through conventional breeding.134
While selective breeding has been used for millennia to shape plants and animals, genetic modification is a more recent development that enables targeted, artificial manipulation of genetic material.452
