[Temperature sensitivity of mutations in species of the virillis group of Drosophila. III. The maternal influence and dominance of lethals in D. virillis Sturt. X D. littoralis Sokolov hybrids].
Lethal mutations sensitive to the temperatures 17 and 31 degrees were found in D. virilis. The phenocritical stage for the heat-sensitive mutation begins from the 2nd half of the 3rd larval instar. The specific stage for the cold-sensitive mutation was not found. The mutations are recessive under intraspecific and interspecific (D. littoralis female XD. virilis hermaphrodite) crossing. They are inherited as dominant in the hybrids D. virilis female XD. littoralis hermaphrodite due to the maternal effect of the D. virillis egg cytoplasm.
