The correct answer is: chromosomal map or genetic map or linkage map
A linkage or genetic chromosome map is a linear graphic representation of the sequence and relative distances of the various genes present in a chromosome. A chromosome map is also called a linkage map or genetic map.

The percentage of crossing over between two genes is directly proportional to their distance. The unit of crossing over has been termed as by Haldane as centiMorgan (cM). One unit of map distance (cM) is, therefore, equivalent to 1% crossing over.
