The Fruitless Gene Influences Female Mate Preference In Drosophila, Tabashir A. Chowdhury
The Fruitless Gene Influences Female Mate Preference In Drosophila, Tabashir A. Chowdhury
Electronic Thesis and Dissertation Repository
Species can arise as a result of reproductive barriers that prevent gene flow between diverging populations that force them to remain isolated from one another. Behavioural isolation is one of the earliest acting reproductive barriers determined by the evolution of mating preferences that prevent inter-specific matings. Several traits have been identified that contribute to behavioural isolation, but the genetic basis of interspecific female preference is yet to be determined. I used genetic mapping techniques to identify and confirm that the fruitless gene is affecting species-specific female rejection of interspecies males, contributing to the behavioural isolation between Drosophila melanogaster and D. …
