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 کاملNatural genetic variation in male reproductive genes contributes to nontransitivity of sperm competitive ability in Drosophila melanogaster.
Female Drosophila melanogaster frequently mate with multiple males, and the success of a given male depends not only on his genotype but also on the genotype of his competitor. Here, we assess how natural genetic variation affects male-male interactions for traits influencing pre- and postcopulatory sexual selection. Males from a set of 66 chromosome substitution lines were competed against eac...

متن کاملSperm precedence in monarch butterflies (Danaus plexippus)
We characterized sperm precedence in monarch butterflies (Danaus plexippus), using a series of experiments in which we manipulated male mating histories to vary spermatophore size and the number of sperm transferred. Several factors affected the outcome of sperm competition. There was a pattern of second-male sperm precedence, but second-male precedence was rarely complete, and several other fa...
