Abstract/Artist's Statement

Aggressive behavior plays a large role in survival across many species. Therefore it is a subject that is often written about and debated over. Recent studies have found associations between genes and behavioral traits. In this project, I explore the relationship between aggressive behavior and genetics. I examined gene expression levels with a qPCR. Using stalk-eyed flies Teleopsis dalmanni I performed aggressive assays to determine behavior, and selected genes from previous studies on aggression and genomics. I chose to use two tissue samples per individual, heads and testes. In this study I found two genes to be significantly differentially expressed, and two more that were marginally significant in flies displaying aggressive behavior. I also found a significant difference of expression between testes and head tissue in one gene.
