Mating-Induced Changes in Behavior and Gene Expression of Female
MetadataShow full item record
Sexual reproduction plays a significant role in how many organisms pass on their genetic information by introducing diversity into the genomes of offspring. With sexual reproduction also comes the opportunity for conflict, however, as females and males counter-adapt to each other to fulfill their own fitness needs. This study uses the nematode Caenorhabditis remanei as a model organism to investigate female responses to mating at both the behavioral and genetic levels. Using behavioral assays and RNAseq, we found that mating causes females to eat more and move less than their virgin counterparts. These adaptations are likely the result of a pathway in response to mating that confers a fitness benefit to these females.
