Original image was decomposed into Gauss … WebBiologic Gradient Biologic gradient refers to the presence of a mono-tone (unidirectional) dose–response curve. We often expect such a monotonic relation to exist. For exam-ple, more smoking means more carcinogen exposure and more tissue damage, hence more carcinogenesis. Such an expectation is not always present, however.
