Users should map back from the entrez gene IDs produced to determine which result is the one they want when this happens. We see individuals with a known or suspected genetic condition or a family history of a known genetic condition. For any two genes (or loci) alpha and beta, we can ask "What is the recombination frequency between them?"If the genes are on different chromosomes, the answer is 50% (independent assortment). The distance between the genes can be written as a percentage or as a MAP UNIT. A genetic map is simply a representation of the distribution of a set of loci within the genome. However, setting up a testcross is not trivial.
