20 cze 2023 · A genetic map shows the map distance, in cM, that separates any two loci, and the position of these loci relative to all other mapped loci. The genetic map distance is roughly proportional to the physical distance, i.e. the amount of DNA between two loci.

By finding recombination frequencies for many gene pairs, we can make linkage maps that show the order and relative distances of the genes on the chromosome.

Recombination frequency and gene mapping. Genes A, B, G, and H are located on the same chromosome. The distances between the genes are below:
Explain why a map is an important aid to genome sequencing. Distinguish between the terms ‘genetic map’ and ‘physical map’. Describe the different types of marker used to construct genetic maps, and state how each type of marker is scored.
