Centimorgan

Definition

noun, plural: centimorgans

A unit of recombination frequency, implying distance along a chromosome.


Supplement

One centimorgan (cM) is equivalent to a 1% chance that a marker at one genetic locus will be separated from a marker at a second locus due to crossover per generation.

In humans, 1 cM is equivalent to (on average) 1 million base pairs.


Word origin: named after geneticist Thomas Hunt Morgan by his student Alfred Henry Sturtevant.

Abbreviation: cM
See also: genetic map.

HELP ME please...ABOUT THIS GENE MAPPING THING

... a line, that is your section of chromosome. Put a mark on it, and name it A. Arbitrarily (and conveniently) define a scale for genetic distance (1 centimorgan= 1centimeter/square/whatever). Then write on a paper the distances between A and B, A and C, and B and C. See which locations for the 3 ...
