    <description descriptionType="Abstract">Sperm competition is a post-copulatory sexual selection mechanism in species in which females mate with multiple males.  Despite its evolutionary relevance in shaping male traits, the genetic mechanisms underlying sperm competition are poorly understood.  A recently originated multigene family specific to D. melanogaster, Sdic, is important for the outcome of sperm competition in doubly-mated females, although the mechanistic nature of this phenotype remained unresolved.  Here we compared doubly-mated females, second mated to either Sdic knockout or non-knockout males, and directly visualize sperm dynamics in the female reproductive tract.  We found that a less effective removal of first-to-mate male's sperm within the female's sperm storage organs is consistent with a reduced sperm competitive ability of the Sdic knockout males.  Our results highlight the role young genes can play in driving the evolution of sperm competition.</description>
    <description descriptionType="Other">&lt;div class="o-metadata__file-usage-entry"&gt;Sperm counts in the reproductive tract of doubly-mated females&lt;div class="o-metadata__file-description"&gt;Assays were performed to evaluate how sperm dynamics in the reproductive tract of doubly-mated females differs when the second-to-mate experimental male is either possessing (Sdic+ ) or lacking (Sdic- ) the entire D. melanogaster-specific Sdic multigene family. Virgin females were first mated to a reference Sdic+ male and then to one of the two possible experimental males (Sdic+ or 
 Sdic- ) two days later. Females were randomly assigned to one of three time points after the end of the second mating period (30 min, 1 h and 45 min, and 2 days) and subsequently flash frozen. Female reproductive tracts were dissected and the sperm from the different males were counted using a fluorescent microscope. Reference and experimental sperm fluoresce red and green, respectively.Sperm counting was performed for the bursa and both sperm storage organs, i.e. the paired spermatheca and the seminal receptacle.&lt;/div&gt;&lt;div class="o-metadata__file-name"&gt;Sperm counts in doubly-mated females.xlsx&lt;br&gt;&lt;/div&gt;&lt;/div&gt;&lt;p&gt;Funding provided by: National Science Foundation&lt;br&gt;Crossref Funder Registry ID:;br&gt;Award Number: MCB-1157876&lt;/p&gt;</description>
