Abstract
The hundreds of cichlid fish species unique to Lakes Malawi and Victoria in Africa can be considered as a natural mutagenesis screen for genes responsible for the origin and maintenance of species. We will screen 8 inter-species crosses for major genes responsible for male courtship colour and female mate preference, and test for the significance of male traits by conducting an assay of female preferences (using microsatellite paternity determination) among F2 males of different colour. The results will provide unique insights into the genetic bases of mate preferences, for species isolation based on visual cues and on rapid speciation in cichlids and will represent a critical first step in the search for speciation genes in cichlids.
