Linkage map

Definition
noun
A genetic map showing the relative positions of genetic markers along a chromosome that is determined by the recombination frequency during crossover of homologous chromosomes.
Supplement
Genetic linkage map shows the relative positions of genetic markers on a chromosome. The positions of genetic markers are determined based on how often the loci are inherited together rather than on the specific physical distance between them. It means that the more often the two genetic markers are inherited together the farther apart they are. In contrast, the lower frequency of being inherited together the smaller the physical distance is between them.
Synonym: genetic map.

See also: genetic locus.
