Mechanisms of conspecific sperm precedence in Drosophila.
The postmating, prezygotic isolating mechanism known as conspecific sperm precedence (CSP) may play an important role in speciation, and understanding the mechanism of CSP is important in reconstructing its evolution. When a Drosophila simulans female mates with both a D. simulans male and a D. mauritiana male, the vast majority of her progeny are fathered by D. simulans, regardless of the orde...

متن کاملConspecific sperm precedence in two species of tropical sea urchins.
Conspecific sperm precedence occurs when females are exposed to sperm from males of multiple species, but preferentially use sperm of a conspecific. Conspecific sperm precedence and its mechanisms have been documented widely in terrestrial species, in which complex female behaviors or reproductive tract morphologies can allow many opportunities for female choice and sperm competition, however, ...
متن کاملConspecific sperm precedence in Callosobruchus subinnotatus (Coleoptera: Bruchidae): mechanisms and consequences.
Conspecific sperm precedence (CSP) has been identified as an important post-copulatory, pre-zygotic mechanism that can act to reduce gene flow between populations. The evolution of CSP is thought to have arisen as a by-product of male and female coevolution in response to intraspecific post-copulatory sexual selection. However, little is known about the mechanisms that generate CSP. When Callos...
