Integrating Genetic and Physical Maps
Captions available
The idea
A complete genome map combines a genetic map's gene order with a physical map's nucleotide distances, since each alone leaves gaps.
In practice
A sequence-tagged site links a genetic marker to a physical map's exact position.
Where people slip
A genetic map gives distances in recombination-derived map units; a physical map gives distances in nucleotides. Both maps include order, differing only in distance units and resolution.
