| Research Abstract |
The goal of this project is to study the association between mate preference and polymorphism in the 5' cis-regulatory region of the ebony gene in Drosophila. The gene codes for an enzyme in the melanin synthesis pathway and is also known to function in the nervous system. Natural variation in the 5' cis-regulatory region was shown to be responsible for the expression level variation in epidermis as well as that in brain. The expression level variation in brain was shown to influence the mating behavior. Therefore, the results indicated that the variation in 5' cis-regulatory region affects mate preference in this species.
