Two genes may share some related exons but also have unique exons.

The frequency of recombinant gametes is half the frequency of crossing over, and the maximum frequency of recombinant gametes is 50%.  Recombinant gamete = Half of the frequency of crossing over

50% = 100%

Linkage mapping

Gene Mapping- Maps based on recombination rates are called genetic maps. 

Physical mapping- Maps based on physical distances are called physical maps.

Both genetic and physical maps provide information about the relative positions of and distances between genes. Genetic maps are based on rates of recombination and are measured in recombination frequencies (centiMorgans or map units).

Recombination frequencies Recombination frequencies can be used to determine the order of the genes on a chromosome and calculate the approximate distances from one gene to another.
