Diverse Mice (IMAGE)
Caption
Mice from a single species but of different breeds, shown here, were used in a new University of Utah study that found genetic diversity, even within one species of animal, can make a virus less virulent or severe as it passes from one mouse to the next. By contrast, the virus replicated faster and became more virulent when it was passed from mouse-to-mouse when the mice belonged to one breed and thus lacked genetic diversity.
