Gene Mapping

Gene mapping involves determining the locations of genes within specific chromosomes. Two methods of gene mapping are used:

  • genetic mapping
  • physical mapping

Genetic mapping is used to determine the relative position of genes within a chromosome. This is measured by whether or not two genes are "linked". If both genes are inherited together they are considered linked. By determining which genes are linked, the relative positions of genes can be worked out.

Physical mapping involves determining the exact position of a specific gene within a chromosome. There are multiple techniques for accomplishing this, including creating cell hybrids for mapping out DNA in specific chromosomes.
