<p class="">A <strong>genetically modified organism</strong> (<strong>GMO</strong>) is any organism whose <a href="https://en.wikipedia.org/wiki/Gene" rel="noopener noreferrer nofollow">genetic</a> material has been altered using <a href="https://en.wikipedia.org/wiki/Genetic_engineering_techniques" rel="noopener noreferrer nofollow">genetic engineering techniques</a>. The exact definition of a genetically modified organism and what constitutes genetic engineering techniques varies widely, with the most common being altered in a way that does "not occur naturally by mating and/or natural <a href="https://en.wikipedia.org/wiki/Recombination_(biology)" rel="noopener noreferrer nofollow">recombination</a>". A wide variety of organisms have been <a href="https://en.wikipedia.org/wiki/Genetic_engineering" rel="noopener noreferrer nofollow">genetically engineered</a>, from animals to plants and microorganisms. Genes have been transferred <a href="https://en.wikipedia.org/wiki/Cisgenesis" rel="noopener noreferrer nofollow">within the same species</a>, across <a href="https://en.wikipedia.org/wiki/Species" rel="noopener noreferrer nofollow">species</a> (creating transgenic organisms) and even across <a href="https://en.wikipedia.org/wiki/Kingdom_(biology)" rel="noopener noreferrer nofollow">kingdoms</a>. New genes can be introduced, or <a href="https://en.wikipedia.org/wiki/Endogenous" rel="noopener noreferrer nofollow">endogenous genes</a> can be enhanced, altered or <a href="https://en.wikipedia.org/wiki/Gene_knockout" rel="noopener noreferrer nofollow">knocked out</a>. GMOs have been used in biological and medical research, production of <a href="https://en.wikipedia.org/wiki/Pharmaceutical_drug" rel="noopener noreferrer nofollow">pharmaceutical drugs</a>, experimental medicine and agriculture, with developing uses in conservation.</p><p>Source: <a href="https://en.wikipedia.org/wiki/Genetically_modified_organism" rel="noopener noreferrer nofollow">https://en.wikipedia.org/wiki/Genetically_modified_organism</a></p>
