Extract

Drosophila melanogaster and D. simulans constitute one of those cases in which two almost identical phenotypes result from different genotypes. In particular, the histology of gametogenesis shows no detectable difference between the two species, nevertheless, the development of the gonads in their hybrids is so upset that invariably sterility results. In these hybrids the germ cells never go beyond the stage of oogonia or spermatogonia.
