WebA linkage map is a graph that shows how frequently markers recombine during homologous chromosome crossover. The more recombination (segregation) occurs between two genetic markers, the further apart they are thought to be. Conversely, the lesser the physical distance between the markers, the lesser the frequency of recombination between them.
