What is a Single Nucleotide Polymorphism?

If two sequences of DNA from the same position along a DNA strand (locus) have a single change between them we call them single nucleotide (one base unit of DNA, A/T/C/G) polymorphism (poly- "many-" -morphism "-form"). Just a way of saying that two DNA strands have a single base change between them.
