Genetic Map is a diagrammatic view of the linear sequence of genes in a chromosome where the space between adjacent genes is corresponding to the rate of recombination (result of crossing over between homologous chromosomes) between them. Genetic mapping has been a vital procedure to separate off and categorise the mutant genes which cause hereditary diseases. Once the position of mutant gene has been located, then it can be used to identify the disease gene and to study its roles.

The unit of distance in genetic map is called a map unit where one map unit is a centimorgan(cM)
