A genetic map, also known as a linkage map, is a diagram of the order of genes on a chromosome. It shows the distance between genes, which is proportional to  the rate of recombination between them. The further apart two genes are on achromosome, the more likely it is that crossing over will occur that causes recombination of the two genes. Genetic maps are important as they show how likey it is that two genes will be inherited together. The unit of distance is a map unit or centrimorgan (cM); one map unit equals one percent recombination[1].
