morgan
n. countablen. a unit used in science to measure how likely it is that genes will stay together when they are passed from parents to children. It helps scientists map where genes are located on a chromosome.
n. a unit for expressing the relative distance between genes on a chromosome. One unit represents a one percent probability that a specific genetic marker will be separated from another due to crossing over.
The distance between these two genes is exactly one Morgan.
Geneticists use the Morgan to calculate the frequency of recombination during meiosis in complex organisms.
While the centimorgan is more frequently cited in modern mapping studies, the Morgan remains the fundamental unit for quantifying the physical linkage between loci on a single chromosome.
Commonly used in its fractional form, the centimorgan (cM), in practical laboratory settings.
