    Allelic asymmetry of the Lethal hybrid rescue (Lhr) gene expression in the hybrid between Drosophila melanogaster and D. simulans: confirmation by using genetic variations of D. melanogaster

    In the cross between Drosophila melanogaster females and D. simulans males, hybrid males die at the late larval stage, and the sibling females also die at later stages at high temperatures. Removing the D. simula...

    Genetic analysis of female mating recognition between Drosophila ananassae and Drosophila pallidosa: application of interspecific mosaic genome lines

    Drosophila ananassae and Drosophila pallidosa are closely related species that can produce viable and fertile hybrids of both sexes, although strong sexual isolation exists between the tw...

    Genetics of Hybrid Inviability and Sterility in Drosophila: Dissection of Introgression of D. simulans Genes in D. melanogaster Genome

    Interspecific crosses between Drosophila melanogaster and Drosophila simulans usually produce sterile unisexual hybrids. The barrier preventing genetic analysis of hybrid inviability and sterility has been taken ...

    Characterization of a reproductive isolation gene, zygotic hybrid rescue, of Drosophila melanogaster by using minichromosomes

    Hybrids carrying the wild type allele of zygotic hybrid rescue (zhr) of Drosophila melanogaster and the maternal cytoplasm of its sibling species (D. simulans, D. mauritiana or D. sechellia) are embryonic lethal,...

    Cytogenetical localization of Zygotic hybrid rescue (Zhr), a Drosophila melanogaster gene that rescues interspecific hybrids from embryonic lethality

    Hybrid females from crosses between Drsophila melanogaster males and females of its sibling species, D. simulans, D. mauritiana, or D. sechellia die as embryos. This lethality is believed to be caused by incompat...

    Hybrid lethal systems in theDrosophila melanogaster species complex

    Lethal phases of the hybrids betweenDrosophila melanogaster and its sibling species,D. simulans are classified into three types: (1) embryonic lethality in hybrids carryingD. simulans cytoplasm andD. melanogaster
