Polymorhpisms and SNPs

From WikiGenetics

Polymorphisms are deviations from the most common (wildtype) alleles, usually in non-coding regions. They are known to be neutral, with no observed loss or gain of function. There are quite useful as molecular markers when groups are trying to find or map new genes. There are many types of sequence polymorphisms, and many ways to test for their presence.
