WebA genetic linkage map describes the position of a species' or experimental population's known genes or genetic markers in terms of recombination frequency rather than a particular physical distance along each chromosome. A linkage map is a graph that shows how frequently markers recombine during homologous chromosome crossover. WebMapping Linkage. Linkage can be assessed by determining how often crossing-over occurs between two genes on the same chromosome. Genes on different (nonhomologous) …
