Definition of Mapping



Mapping is an experimental procedure in which the relative locations of the genes and the other fragments of the DNA are determined. The genetic mapping makes us clear about whether the disease that is being transmitted to the offspring from the parents is linked to other genes or not. It also tells us where the gene is located on the chromosome.

 


The significance of the Human Genome Project lies in the better and cheaper development of tools by which the new genes can be identified and their functions can be precisely understood. Through genetic mapping, the uncommon, single-gene inherited disorders like cystic fibrosis, etc. are determined.
