nic animals, i.e., engineered to carry genes from other species, have the POTENTIAL to improve human welfare in:agriculture, such as larger sheep that grow more woolmedicine, such as cows that produce INSULIN in their milkindustry, such as goats that produce spider silk for materials productionTransgenic mice, rats, rabbits, PIGS, sheep, and cows have already been created.A natural protein produced in the milk of transgenic cows like this one kills the bacteria that cause animal MASTITIS. Source: USDA.Nowadays, breakthroughs in molecular biology are happening at an unprecedented rate. One of them is the ability to engineer transgenic animals, i.e., animals that carry genes from other species. The technology has already produced transgenic animals such as mice, rats, rabbits, pigs, sheep, and cows. Although there are MANY ethical issues surrounding transgenesis, this article focuses on the basics of the technology and its applications in agriculture, medicine, and industry.
