;<span id="centimorgan">Centimorgan</span>:
:In [[#DNA|DNA]] analysis, a [https://wikipedia.org/wiki/Centimorgan centimorgan] (abbreviated cM, or cMs plural) is a unit for measuring genetic commonality. It describes a distance between loci (also termed chromosome positions or markers) where blocks of the chromosome tend not to break apart for recombination. In that block, the predicted frequency of intervening chromosomal crossovers is 0.01 over a single generation. While it is often used to infer distance along a chromosome, it is not a true physical distance. An alternative term is map unit (abbreviated m.u.) but this alternative form is less frequently seen in genealogy forums.
