Using a model with two genetic types, biologists at the Institute of Research for Development in Montpellier, France, are attempting to understand the theory that Peto's paradox, the absence of a correlation between likelihood of cancer and an animal's body mass, could be attributed to the larger animal's ability to protect itself against the disease.
