Unit of measurement for studying genetics. One centimorgan is equivalent to a 0.01 chance that a particular genetic location (locus) will be separate from a particular marker in a single generation. In humans a centimorgan is about 1 million base pairs.

A unit used to express distances on a genetic map. In genetic mapping, distances between markers are determined by measuring the rate of meoitic recombination between them, which increases proportionately with the distance separating them. A cM is defined as the length of an interval in which there is a 1% probability of recombination. On the average, 1 cM is roughly equivalent to 1 megabase (Mb) of DNA, although this can vary widely due to hot and cold spots of recombination.

A measure of the frequency of genetic recombination. A centimorgan is a unit of genetic mapping equal to 1% crossover of genes between homologous chromosomes as established by genetic studies.

A unit of measure of genetic distance. One centimorgan is equal to a 1% chance that there will be a recombination between two loci. In human beings, 1 centimorgan approximates, on average, 1 million base pairs.

The unit of linkage that refers to the distance between two gene loci determined by the frequency with which recombination occurs between them. Two loci are said to be one centimorgan apart if recombination is observed between them in 1% of meioses.

A measure of distance between two genes based on the frequency with which they are inherited together. 1 cM is equivalent to a 1% frequency of recombination and approximately to 1 megabase.

The metric used to describe linkage distances. A centimorgan is the distance between two genes that will recombine with a frequency of exactly one percent. This term is named afer Thomas Hunt Morgan, who first conceptualized linkage while working with Drosophila. See Centimorgan in the MGI Glossary.

A unit of measure of recombination frequency used in genetic maps. One centiMorgan represents a 1% chance that a marker at one genetic locus will be separated from a marker at a second locus due to crossing over in a single generation. In humans, one centimorgan is equivalent, on average, to one million base pairs.

A measure of the statistical probability of recombination between alleles. One cM represents 1% chance of recombination per meiotic event.

A measure of genetic distance that tells how far apart two genes are. Generally one centimorgan equals about 1 million base pairs.

Measure of genetic distance between two loci based on the number of recombination events occurring between them, 1cM = roughly 1 x 106 base pairs

A unit of measure of recombination frequency. One centimorgan is equal to a 1% chance that a marker at one genetic locus will be separated from a marker at a second locus due to crossing over in a single generation. In human beings, 1 centimorgan is equivalent, on average, to 1 million base pairs.

(cM) A unit of measure of recombination frequency.

The unit of measurement for distance and recombinate frequency on a genetic map. Formally, the length (number of bases) that have a 1% probability of participating in mixing of genes. For humans, the average length of a cM is one million base pairs (or 1 megabase, Mb).

Unit used to measure map distances, equivalent to a 1% chance of recombination (crossing over).
