From Wikipedia, the free encyclopedia
Gene mapping describes the methods used to identify the position of a gene in a genome and the distances between genes. Methods of gene mapping have changed over time with the application of new molecular biology-based technologies (cloning, DNA sequencing, etc). and can varied between different species, i.e. Human genes are mapped differently than Drosophila genes.[2]

Gene mapping results in the production of either genetic or physical maps depending on the methodologies being used. Gene mapping often starts with assigning a particular gene to a given chromosome.
