Last mated male sperm precedence in doubly mated females is not ubiquitous: evidence from sperm competition in laboratory populations of Drosophila nasuta nasuta and Drosophila nasuta albomicans

Drosophila has been extensively used as a model of choice to investigate the phenomenon of sperm competition. Availability of genetic markers and feasibility of its study in natural populations have enabled the proposal of various theories and models to explain the importance of this complex phenome...

Description
Summary:Drosophila has been extensively used as a model of choice to investigate the phenomenon of sperm competition. Availability of genetic markers and feasibility of its study in natural populations have enabled the proposal of various theories and models to explain the importance of this complex phenomenon. Most of the studies involving various species across taxa have shown that the sperm contributed by the latest male are more successful in fertilizing the eggs of a multiply mated female.
