A genetic map is a type of chromosomal map that shows the relative location of genes and other important characteristics. The map is based on the concept of linkage, which means how close two genes are on the chromosome, the mayor will be the probability that they are inherited together. Following the inheritance patterns, the relative location of the genes throughout the entire chromosome can be established.

Illustration

[A genetic map] is a map that shows the relative location of two genetic traits. And the way to determine this is to use the descendants of an organism and keep track of how many times two genetic traits specify here together, for example, hair color and eye color. The higher the percentage of the descendants that have both characteristics at the same time, the closer to the chromosome the genes responsible for the characteristic characteristics.
