โฆ Synopsis
Inversion polymorphism has been studied in three natural populations of Droso~~iIa anana~sae. The three cosmopolitan inversions have been detected in all the three populations analysed. Some quantitative variations in the inversion frequencies seem to exist and the level of inversion heterozygosity varies between the different populations.

Drosophila ananassae is a cosmopolitan and domestic species. It occupies a unique status among the Drosophila species due to certain peculiarities in its genetic behaviour. The most unusual feature of this species is spontaneous male recombination in appreciable frequency. The present review summari
Crosses were made between geographic races of Drosophila ananassae from different localities in India. All these strains employed in the present experiments were polymorphic for the gene arrangements in the second chromosome due to the occurrence of alpha (subterminal) inversion. After ten generatio
We have sampled wild chromosomes from two natural populations of Drosophila melanogaster and obtained flies fully homozygous for the second chromosome, the third chromosome, or both, as well as flies heterozygous for one or both wild chromosomes and balancer chromosomes. Rate of embryogenesis (egg l
