Within this group, each diagnostic allozyme is expected to mark the taxonomic origin of a linkage group. Assuming that the allozyme markers are not linked, these linkage groups are expected to son independently of one another, and it is possible to determine whether an appreciable portion of the physiological variation cosegregates with any of the genetic markers.

Under the GROUP command at the minimum LOD = 3 and the maximum distance of 25 cM between 2 loci, markers were organized into linkage groups. Successive COMPARE, ORDER, and MAP commands were used to order the markers preliminarily in each linkage group with fewer than 9 markers.
