gene mapping

ge·net·ic map

an abstract representation of the ordered array of genetic loci such that the interval between entries has algebraic signs and magnitude proportional to the expected number of crossings over between them and distances are algebraically additive; for example, on a genetic map the combined distance between locus A and locus C is the algebraic sum of the two distances between loci A and B, and B and C.

gene mapping

Determining the location of hereditary information carried on chromosomes. In humans, this requires determining the base pairs (chemical code) of each of the estimated 20,000 to 25,000 genes. Once a gene is mapped, that information may be used to compare abnormal genes with normal ones. Molecular biological techniques may then be used to search for methods of treating and preventing conditions resulting from genetic abnormality.
Synonym: genome mapping; linkage map See: gene splicing
