What is the difference between a linkage map and a physical map?

#Unit 11. Evolution and Behavior

  1. For a linkage map, markers are spaced by recombination frequency, whereas for a physical map they are spaced by numbers of base pairs (bp).

  2. For a physical map, the ATCG order and sequence must be achieved, but not for the linkage map.

  3. For a linkage map, it is shown how each gene is linked to every other gene.

  4. For a physical map, the distances must be calculable in units such as nanometers.
