A linkage map, also known as a genetic map, is a type of chromosome map that shows the relative positions of genes on a chromosome. It is based on the principle of linkage, which describes how the physical proximity of genes on a chromosome affects their inheritance patterns. By analyzing the frequency of recombination events between genes, scientists can construct a linkage map that indicates the relative distance between genes and their order on a chromosome. Linkage maps are important tools for studying gene function, identifying disease-causing mutations, and exploring the evolutionary history of species.
