Nasonia vitripennis, Developmental genetics
Nasonia vitripennis is a relatively new model organism in the field of developmental genetics. It is a small, solitary, parasitic Hymenopteran found throughout the world. Recent research on Nasonia has primarily dealt with its mode of sex determination, and the reproductive isolation of species of Nasonia by a parasitic bacteria, Wolbachia (Werren 94). Like many Hymenopterans, Nasonia uses the haplo-diploid method of sex determination. In haplo-diploid organisms, fertilized eggs produce diploid females while unfertilized eggs produce haploid males. The system is a bit of a mystery, as it is possible to obtain fertile diploid males by setting triploid females unmated. In some Hymenoptera, sex is determined by the number of different copies of certain genes. Fertilized eggs have produced males after extensive inbreeding. This does not appear to be true in Nasonia, however, as much back-crossing has been done without ever producing a single male from a fertilized egg (Bull 1983).
