| Research Abstract |
In Drosophila melanogaster, sexually dimorphic projection pattern is seen in the taste neurons on tarsus of the forelegs. We identified the projection pattern of each taste neuron. Results showed that the neurons with some specific bristles in males have male-typical projection. Two sex determination factors, Fruitless and Doublesex, regulate the formation of male-specific projection pattern. Loss of function of Fruitless or Doublesex caused males having female-type of the projection pattern. They showed the normal activity of courtship still.
