You are working with a 125 million bp human chromosome (1 centimorgan = 1 million bp), and wish to use markers to map newgenes via linkage. In theory, what are the minimum number of markers/loci you need to map genes to this chromosome? Why?

    After every 0.192 centimorgan

    Explanation:

    If there are 125 million base pairs then according to the parallel ratio compare rule it should contain an average of 650 genes. If every gene has to be marked by a single marker on each end then a total number of 651 markers are used after every 0.192 centimorgan distance.
