![]() ![]() Is it morally acceptable to genetically modify farm animals?.Is genetic modification of farm animals ethical?.Do the benefits of genetically modified farm animals outweigh the risks?.Below are some of the advantages and disadvantages associated with genetically modifying animals for agriculture, divided up into four key areas: The majority of work on genetically modified farm animals is still in the research phase and is yet to be used commercially. For example, cows, goats and sheep have been genetically engineered to express specific proteins in their milk. These can include milk production and disease resistance, as well as improving the nutritional value of the products they are farmed for. However, farm animals, such as sheep, goats and cows, can also be genetically modified to enhance specific characteristics. Genetically engineered animals enable scientists to gain an insight into basic biological processes and the relationships between mutations and disease. ![]() The most widely used genetically modified animals are laboratory animals, such as the fruitfly ( Drosophila) and mice. Researchers have genetically engineered a number of mammals, from laboratory animals to farm animals, as well as birds, fish and insects. The number of genetically modified animals used in agriculture has increased significantly in recent years.
