Summary Introduction
Introduction: Gene mapping is usually used to identify or locate the position of a specific gene and also to measure the distance between two genes in a chromosome. It is a graphical representation of the genes or sequences of DNA that are present on the chromosome. Gene mapping plays a vital role in identifying the expression of genes responsible for a disease and its inheritance pattern.
