a centimorgan is a unit of genetic distance. Two loci are 1 cM apart if there
is a 1% chance of recombination between them in a given meiotic event.

The relation to physical distance is not truly linear becuase of recombination
hotspots average chromosome contains about 150cM, there are about
3300cM in the whole human genome. Therefore, on average, 1cM is about 1
million bp (1000kb)

...found definition in Priniciples of Medical Genetics...
