Two genes is easy, but how do youdo three genes? I can figure out the distance from each gene to thecentromere, but I don't know how to figure out the distancesbetween the genes themselves. Normally the equation is:

distance = (0.5TT + NPD)/total and then times by 100 to get the mapunits. But the problem is, if I use this same equation for eachgene, all genes will have the exact same distances. How do I changeit so that they have the correct distances?
