Figure 8.1 Conceptual depiction of the laboratory animal and how its biology, while based on genetics, is readily influenced by environmental factors. Controlling these environmental factors, any of which may confound animal research data, is a major component of laboratory animal science. (From Baker, H.J., Lindsey, J.R., and Weisbroth, S.H., Housing to control research variables, in The Laboratory Rat: Vol. I, Biology and Diseases, Baker, H.J., Lindsey, J.R., Weisbroth, S.H., Eds., Academic Press, New York, 1979, pp. 169-192.

These categories do not pertain to any particular species; however, the descriptions in this chapter pertain primarily to standard laboratory animals.
