A genetic map (also called a linkage map) shows the relative location of genetic markers (reflecting sites of genomic variants) on a chromosome. A genetic map is based on the concept of genetic linkage: the closer two markers are to each other on a chromosome, the greater the probability that they will be inherited together. By studying inheritance patterns, the relative order and location of genetic markers along a chromosome can be established.

Genetic Map. So, genetic map tells us the location of each gene on the chromosome. It is like having the address of each house along a street. It helps us to appreciate how genetic markers along the chromosome may be inherited together. Closer markers are more likely to be inherited together. And sometimes we refer to this as "blocks."
