centimorgan

In the Human genome, the centimorgan is about 1 million base pairs.

Note that the parent unit of the centimorgan, the morgan, is rarely used today.

One centimorgan corresponds to about 1 million base pairs in humans on average.

A centimorgan (cM) is a unit that describes a recombination frequency of 1%.

The Centimorgan is also often used to imply distance along a chromosome, but the number of base pairs it corresponds to varies widely.

He mapped the mutations to the same location on the far left of the X chromosome, less than 1 centimorgan away from the white gene locus.

The overall recombination rate is 9.6 kilobase per centimorgan and 54 candidate recombination hotspots have been identified.

Morgan (unit), a unit of recombinant frequency in genetics (the centimorgan is most frequently used)

In genetics, a centimorgan (abbreviated cM) or map unit (m.u.) is a unit for measuring genetic linkage.

The centimorgan was named in honor of geneticist Thomas Hunt Morgan by his student Alfred Henry Sturtevant.

The chromosome lengths are based on the centimorgan (cM) scale as shown on the TAIR Map Overview [ 62].

A gene encoding an ATP-binding cassette transporter was mapped to the 2-cM (centiMorgan) interval at 1p13-p21 previously shown by linkage analysis to harbor this gene.

This distance is called a genetic map unit (m.u.), or a centimorgan and is defined as the distance between genes for which one product of meiosis in 100 is recombinant.

The disease was initially linked to an 8 centiMorgan region spanning the centromere of chromosome 12, and then further refined to a critical region of 3 cM [ 1, 2].

The BXD strains are associated with approximately 1,500 recombinations, an average of about 42 per strain, and approximately one recombination per centimorgan on a standard genetic map (Tables 2, 3).

Within 100 generations in humans (about 2100 years in ancient times) one expects a few hundred of these 'blending' events to have occurred across a single chromosome, the average size is 1 centiMorgan (or 1 cM).

For an RI strain to be useful for mapping purposes, the approximate position of recombinations along each chromosome need to be well defined either in terms of centimorgan or DNA basepair position.

Plasmodium falciparum has an average recombination distance of 15 kb per centimorgan: markers separated by 15 kb of DNA (15,000 nucleotides) have an expected rate of chromosomal crossovers of 0.01 per generation.

Morgan proposed that the amount of crossing over between linked genes differs and that crossover frequency might indicate the distance separating genes on the chromosome; later English geneticist J. B. S. Haldane suggested that the unit of measurement for linkage be called the centimorgan.
