Developing a vaccine for polio using mice. Testing a weedkiller on rats and dogs. Animals need to be bred with special characteristics for use in research. What is animal research?

To gain an understanding of how genes work. This might help develop treatments for genetic disorders. So vaccines can be developed to protect people from illness So lots of animals with the same characteristics are available for research Why?
