FAQs on Transgenic Animals

Q1. What are transgenic animals?

Answer: Transgenic animals are animals that have been genetically engineered to possess a trait or traits that are not naturally found in that species. The introduced genetic material may come from another species, or it may be man-made.

Q2. What are some examples of transgenic animals?

Answer: The first transgenic animal was a mouse, created in 1974. Transgenic mice are now commonly used in research. Other examples of transgenic animals include cows, pigs, goats, fish, and chickens.

Q3. What are some potential benefits of transgenic animals?

Answer: Transgenic animals may be used to produce pharmaceuticals and other valuable proteins in their milk, eggs, or blood. They may also be used to create model organisms for studying human diseases, and for developing new methods of agriculture and animal husbandry.

Q4. What are some potential risks of transgenic animals?

Answer: There is always the potential for unintended consequences when introducing new genes into an animal. There is also the possibility that transgenic animals could escape and mate with wild animals, causing unforeseen environmental impacts.
