In all the experiments, the continuous confinement technique was used. The comparison of productivity between once-mated (control) and remated females reveals that the productivity of remated females is significantly higher than that of once-mated ones in all the crosses. The P2´ values (the proportion of second male progeny produced after remating) were calculated to test sperm displacement in each cross of remated females. In all the crosses, high P2´ values (0.91–0.94) were found which indicate sperm precedence of second male to mate suggest-ing the existence of sperm displacement in D. ananassae. Furthermore, female productivity is increased after remating in D. ananassae.","http://cogprints.org/1948/","Singh, Shree Ram","UNSPECIFIED"," Singh, Shree Ram (2001) Female remating in Drosophila ananassae: evidence for sperm displacement and greater productivity after remating.
