WebEvolution impinges on physiology in many different ways, and one of the ways to study that is to look at phenotypic plasticity. So, a genotype is the genetic makeup, whereas the phenotype is a resulting morphology and physiology. In many cases a single genotype can generate more than one phenotype; this is called polyphenism or phenotypic ...
