WebThe coupling phase analyzed a total of 2839 gametes, and of these gametes 305 (151 pr+ vg + 154 pr vg+) gametes were recombinant. To determine the linkage distance simply divide the number of recombinant gametes into the total gametes analyzed. So the linkage distance is equal to 10.7 cM [ (305/2839)*100)].
