Polymorphism Definition & Meaning - Merriam-Webster

A polymorphism can be any sequence difference. Examples include: • Single nucleotide polymorphisms (SNPs) are a single nucleotide changes that happen in the genome in a particular location. The single nucleotide polymorphism is the most common form of genetic variation. • Small-scale insertions/deletions (Indels) consist of insertions or deletions of bases in DNA.
