It was found that the distances of the map constructed with the software were often exaggerated when large number of markers was involved. The present paper is to introduce our technical experiences in using Method 2 (marker number more than 500) of the software for a more reasonable linkage map. In Method 2 of Mapmaker/Exp (3.0), markers were usually grouped into linkage groups under an identical LOD value for all linkage groups; and then an “order” command followed by multiple “ripple” command
