the way these experiments are done they're it's pretty much the same principle is that you take in the case of rats or mice which you have this luxury you can cross one strain of mouse or rat to another strain of mouse or rat and then look for signposts of genetic variation along the entire genome of the animal and each strain has different sequences of DNA prime major differences are in this so-called non-coding region some of the differences are in coding regions
