The coexistence of multiple alleles at a locus in a population is called genetic polymorphism. A locus is usually defined as polymorphic if two or more alleles are present at a frequency of more than 1% in the population.

RFLPs and SNPs can be the basis for linkage maps and are useful for establishing parent–offspring relationships.

Sections of DNA that are conserved among species can be identified by performing a zoo blot. We use short fragments from the region as labeled probes to test for homologous DNA from a variety of species by Southern blotting.

Technique that allows genomic fragments to be rapidly scanned for the presence of exons is called exon trapping.
