Abstract

With the aid of species hybrids between two Drosophila species it is shown that cooperative interactions between species specific genes occur during spermatogenesis. It is however possible to incorporate fertility genes of one species into the genome of the other species and to functionally substitute homologous genes of the host species. Thus, the foreign genes can still be regulated and in some cases their gene products remain functional although considerable evolutionary changes can be observed between both species. Such changes include alterations in the positions of the respective genes in the genome as well as transcriptional properties (i.e., the morphological structure of lampbrush loops).
