Determining the relative positions of genes on a chromosome and the distance between them. Gene mapping is crucial to understanding and developing treatments for genetic disease.
There are two different methods of gene mapping:
Physical mapping involves finding the exact position of a specific gene within a chromosome. Various techniques have been developed to do this, including creating cell hybrids for mapping out DNA in specific chromosomes.
