Role of the female genotype in the formation of structural anomalies in the organs of Drosophila virilis female times D. litoralis male hybrids.

The role of the female genotype of Drosophila virilis in the formation of structural anomalies of the organs in the progeny after crossing with D. litoralis males was studied. The frequency of appearance and the character of the anomalies are shown to depend on the genotype of the original maternal line.
