| Abstract | Natural populations and their mass culture stocks of Drosophila ananassae were analyzed for the frequencies of three cosmopolitan inversions. The frequency of ST gene rearrangement was recorded to be high in both natural populations as well as in the mass culture stocks. Furthermore, out of three cosmopolitan inversions, the AL and DE had higher occurrence showing their adaptive significance to this species. ET inversion that persists in all populations, was thinly represented than the other two. These natural populations, coming from different geographical localities, showed very little genetic variation. The mass culture stocks also showed almost similar genetic composition as their respective natural populations. Various parameters of population genetics were computed in order to find out genetic structure of the natural populations. The results indicate that genetic changes in the natural populations have scarcely undergone, and no significant genetic differentiation could be observed when natural populations were compared with the respective mass culture stocks. |
