Mor·gan

(mōr'găn),
Harry de R., British physician, 1863-1931. See: Morgan bacillus.

mor·gan (M),

(mōr'găn),
The standard unit of genetic distance on the genetic map: the distance between two loci such that on average one crossing over will occur per meiosis; for working purposes, the centimorgan (0.01 M) is used.
[T.H. Morgan, U.S. geneticist, 1866-1945]

map unit

An arbitrary unit for the distance between genes, usually derived from the percentage of recombination, but also defined by the time at which the gene is transferred during conjugation. One map unit corresponds to a recombination frequency of 1%.

centimorgan

A unit of distance between two genes on a chromosome, representing a 1 per cent probability of recombination in a single meiotic event. Named after Thomas Hunt Morgan (1866–1945) the American Nobel-prizewinning geneticist often described as the father of modern genetics.

centimorgan

a measure of the degree of recombination between two genes. One centimorgan is approximately 1000 kilobases. Named after T.H. Morgan. See also genetic map.
