Anomalies in the expression profile of interspecific hybrids of Drosophila melanogaster and Drosophila simulans.
When females of Drosophila melanogaster and males of Drosophila simulans are mated, the male progeny are inviable, whereas the female progeny display manifold malformations and are sterile. These abnormalities result from genetic incompatibilities accumulated since the time the lineages of the species diverged, and may have their origin in aberrant gene transcription. Because compensatory chang...
متن کاملVariable modes of inheritance of morphometrical traits in hybrids between Drosophila melanogaster and Drosophila simulans.
We investigated body-size inheritance in interspecific sterile hybrids by crossing a Drosophila simulans strain with 13 strains of Drosophila melanogaster, which were of various origins and chosen for their broad range of genetic variation. A highly significant parent-offspring correlation was observed, showing that the D. melanogaster genes for size are still expressed in a hybrid background. ...

متن کاملThermal plasticity of wing size and shape in Drosophila melanogaster, D. simulans and their hybrids
Populations of Drosophila melanogaster, as well as of other Drosophila species, show body size differences according to their geographic origin. Thermal selection is considered to be the most likely cause explaining these differences. We investigated wing size, wing shape and their relationship in 3 different geographic populations of D. melanogaster, 1 population of D. simulans, and their inte...
متن کاملRelative paucity of genes causing inviability in hybrids between Drosophila melanogaster and D. simulans.
Using deficiencies from Drosophila melanogaster, we looked for genomic regions in the sister species D. simulans that could cause lethality when hemizygous on a hybrid genetic background. Such genotypes allow hemizygous genes from one species to interact with heterozygous genes from other species and may correspond to the kinds of genotypes causing Haldane's rule, the observation that if only o...
