Abstract
The P-M system of hybrid dysgenesis in Drosophila melanogaster was inv estigated on the basis of gonadal dysgenesis, using 1,590 strains from 28 natural populations in Japan, and 20 populations from Southeast As ia, the Pacific area and Africa. Strong P strains were found sporadica lly in several populations in Japan, Few strong M strains were observe d. Q strains were present at a high frequency in most populations. Thu s, most populations in these areas were regarded as Q populations. The distribution of the P element and the evolution of P, Q and M populat ions are also discussed.
