Physical map
From Wikipedia, the free encyclopedia
A physical map can refer to:
- A physical map (cartography) shows identifiable landmarks such as mountains, rivers, lakes, oceans, and other permanent geographic features.
- A physical map (genetics) tells you how much DNA separates two genes and is measured in base pairs, as opposed to a genetic map which tells you the positions of genes in relation to each other based on the frequency of crossing overs (recombinant frequency).
