In linkage maps, you may see distances expressed as centimorgans or map units rather than recombination frequencies. Luckily, there's a direct relationship among these values: a 1 % recombination frequency is equivalent to 1 centimorgan or 1 map unit.
Calculating map distance between two genes is an indispensable tool in genetic research and molecular biology. By understanding recombination frequency and converting it into map distance, you can gain valuable insights into gene locations on a chromosome.
Use the distance to construct genetic maps based on data from two-point or three-point testcrosses. Loci are locations of genes on chromosomes In many genetic crosses involving one or two genes, the gene can be representing by a name or a letter.
The units of genetic distance are called map units (mu) or centiMorgans (cM), in honor of Thomas Hunt Morgan by his undergraduate student, Alfred Sturtevant, who developed the concept of genetic maps. Geneticists routinely directly convert the recombination frequencies of two loci into cM.

Physical Maps. A physical map provides detail of the actual physical distance between genetic markers, as well as the number of nucleotides. There are three methods scientists use to create a physical map: cytogenetic mapping, radiation hybrid mapping, and sequence mapping.
Discover the fascinating world of genetic recombination and gene mapping. Learn how the distance between genes on a chromosome influences their likelihood to recombine. Dive into the concept of centimorgans, the unit of measurement for gene distance, and how it relates to the frequency of recombination. Created by Efrat Bruck.
