* Research: GM animals are often used in research to study the function of genes and to develop new treatments for diseases. For example, GM mice have been used to study the role of specific genes in obesity, cancer, and Alzheimer's disease.
* Agriculture: GM animals can be created to have desirable traits for agriculture, such as increased milk production, resistance to disease, or improved meat quality. For example, GM pigs have been developed that are resistant to a virus that causes porcine reproductive and respiratory syndrome (PRRS), a costly disease for the pork industry.
* Companion animals: GM animals can also be created as companion animals, with desired traits such as hypoallergenic fur or a specific coloration. For example, GM cats have been developed that are hypoallergenic, making them less likely to cause allergic reactions in people.
The creation of GM animals is a controversial topic, with some people raising concerns about the safety and ethical implications of this technology. However, GM animals have the potential to provide significant benefits to society, and research in this area is continuing.
