| wolbachia and genetic variability in the birdnest blowfly protocalliphora sialia. | wolbachia are widespread cytoplasmically inherited bacteria that induce various reproductive alterations in host arthropods, including cytoplasmic incompatibility (ci), an incompatibility between sperm and egg that typically results in embryonic death. ci has been invoked as a possible mechanism for reproductive isolation and speciation in arthropods, by restricting gene flow and promoting maintenance (and evolution) of genetic divergence between populations. here we investigate patterns of wolb ... | 2003 | 12803636 |
