A genetic map (also called a linkage map) shows the relative location of genetic markers (reflecting sites of genomic variants) on a chromosome. A genetic map is based on the concept of genetic linkage: the closer two markers are to each other on a chromosome, the greater the probability that they will be inherited together. By studying inheritance patterns, the relative order and location of genetic markers along a chromosome can be established.

A physical map, as related to genomics, is a graphical representation of physical locations of landmarks or markers (such as genes, variants and other DNA sequences of interest) within a chromosome or genome. A complete genome sequence is one type of physical map. Physical maps are used to identify genes or other sequences believed to play a role in health conditions or diseases. They are also valuable in providing an organizational framework for generating complete sequences of genomes.
