A variation in the DNA that is too common to be due merely to new mutation. A polymorphism must have a frequency of at least 1% in the population. Examples of polymorphisms include the genes for sickle cell disease, thalassemia and G6PD deficiency. These genes are widely believed to offer an advantage against malaria.

A common change in the genetic code in DNA. Polymorphisms can have a harmful effect, a good effect, or no effect. Some polymorphisms have been shown to increase the risk of certain types of cancer.

(pol-ee-mor-fiz-um) [Gk. polus, many + morphe, form] The coexistence of two or more distinct forms of individuals (polymorphic characters) in the same population.

Polymorphism involves one of two or more variants of a particular DNA sequence. The most common type of polymorphism involves variation at a single base pair.
