No evidence of mitochondrial genetic variation for sperm competition within a population of Drosophila melanogaster.

abstract：:The effects of inbreeding on sperm quantity and quality are among the most dramatic examples of inbreeding depression. The extent to which inbreeding depression results in decreased fertilization success of a male's sperm, however, remains largely unknown. This task is made more difficult by the fact that other factor...
