What is the difference between a linkage map and a physical map?
a.) For a linkage map, markers are spaced by recombination frequency, whereas for a physical map they are spaced by numbers of base pairs.
b.) For a physical map, the ATCG order and sequence must be achieved, but not for the linkage ap.
c.) For a linkage map, it is shown how each gene is linked to every other gene.
d.) For a physical map, the distances must be calculable in units such as nanometers.
e.) There is no difference between the two except in the type of pictorial representation.
