A mutation is defined as any change in a DNA sequence away from normal. This implies there is a normal allele that is prevalent in the population and that the mutation changes this to a rare and abnormal variant. In contrast, a polymorphism is a DNA sequence variation that is common in the population.
What is the difference between single nucleotide polymorphism and mutation?
A SNP is a particular kind of mutations; other kinds involve larger changes to the DNA (like large-scale duplications or deletions, translocations, etc. A SNP is a polymorphic base where the point mutation has persisted in the population. The term point mutation can occur as a one off event in only one individual.
What does polymorphism mean in genetics?
Polymorphism
= 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. Polymorphisms can also be much larger in size and involve long stretches of DNA.
