Electronic Theses and Dissertations

In Drosophila, the male courtship ritual is stereotyped and under the control of several genes including fruitless. In previous studies, it has been show that various fruitless alleles cause phenotypic abnormalities in the D. melanogaster courtship ritual. It is also known that there is a high level of co-expression of both the fruitless gene product and serotonin in specific neurons of the Drosophila CNS. This study examines the role of serotonin in the Drosophila male courtship ritual by using a mutant strain, Ddc^ts1,in which the production of serotonin is blocked above 30°C. In this study an increase in temperature caused …
