CentiMorgan is defined as the distance between genes on the chromosome and is used to measure the recombination frequency.
Introduction
It is a map unit used to measure the genetic linkage, which is defined as the distance between two positions along the chromosome that results in 1% recombinant individual out of 100 progenies. The distance corresponding to this 1% recombination frequency is called centiMorgan (cM) (Lodish et al. 2004).
The term centiMorgan is given to genetic unit in honor of the great scientist Thomas Hunt Morgan.
If two loci are 1 cM apart, then a crossover occurs between them at an average of 1 in 100 meiosis. Therefore, cM is a measure of the genetic or linkage distance between two loci. One map unit is equal to 1 cM and 1 cM is equal to 1% recombination. Thus, two genes that recombine with a frequency of 3.5% bare said to be located 3.5 map units apart. This is not the same as physical...
