Centimorgans, Map units and Crossing-Over

In genetics, a centimorgan (abbreviated cM) or map unit (m.u.) is a unit for measuring genetic linkage. It is defined as the distance between chromosome positions (also termed loci or markers) for which the expected average number of intervening chromosomal crossovers in a single generation is . #genetics #geneticLinkage #crossingOver #gene #Allele
