This seems to be the case particularly for those utilizing isogenic strains of mice, not only because such strains display wide­ ly different phenotypes, but because scientists, by definition, are an inquisi­ tive lot and it is sometimes difficult for the uninitiated to comprehend how such phenotypes are produced. This bewilderment becomes even more ap­ parent if the investigator happens to be...
