One advantage of models is that all the mice are exactly alike except for color, enabling the control of some variables including the one being studied. Models are also easier to work with than live mice. One disadvantage of using models is that they do not have the same smell and behavior as real mice?.

The question is written below:

A team lead by evolutionary biologist Hopi Hoekstra set out to test the hypothesis that predators are an agent of natural selection on mouse color. They made 250 plasticine models of mice that were alike in every way except that half were painted white and half were painted brown. Suggest one advantage and one disadvantage of using model mice instead of real mice in this experiment.
