✦ Synopsis
The F-M system of hybrid dysgenesis was investigated in two Japanese regions, Katsunuma and Qhzu. Most strains were Q in that they did not produce appreciable gonadal dysgenesis with P males or with M females. A few strains produced ambiguous results. Some of these were unstable and on later testing were P, Q or M. Eleven laboratory strains which had been derived from various sites in Japan and had been maintained for 8 to 27 years were also examined. Eight (including all four that were 27 years old) were M, two were Q, and one which had been kept as a large cage population showed some P activity.
