Which practice involves creating organisms that have altered genes for specific benefits?

The practice of creating organisms that have altered genes for specific benefits is known as creating transgenic organisms. This process involves introducing a gene from one species into the genome of another species to confer desirable traits, such as resistance to pests, improved nutritional content, or enhanced growth rates. The technology used for this genetic modification allows for precise manipulation of an organism's genetic makeup, enabling scientists and researchers to enhance specific characteristics in crops and livestock.

Transgenic organisms are commonly used in agriculture, where genetically modified crops can offer benefits like increased yield, reduced reliance on chemical pesticides, and improved resilience to environmental stressors. This field of biotechnology has led to significant advancements in food production and disease resistance, making it a pivotal practice in modern agriculture.

In contrast, selective breeding is a natural process where organisms with favorable traits are chosen to reproduce, but it does not involve direct alteration of genetic material in the same way as genetic engineering does. Sous vide is a cooking technique that involves vaccuum-sealing food and cooking it in low-temperature water, while coulis is a sauce made from pureed fruits or vegetables. These options do not relate to genetic modification or the creation of organisms with altered genes.
