As a rule, progeny of crosses between Drosophila simulans females and D. melanogaster males are formed by sterile males, because females die as embryos. However, populations of these species have been found that produce a certain frequency of viable hybrid females. We have found that 94% of the females of a D. simulans population from Tel Aviv gave hybrid progenies with both sexes. The segregation of phenotypes with different rescue success adjusts to the action of a single, dominant, zygotic… Expand
Genetics of Drosophila simulans male mating discrimination in crosses with D. melanogaster
TLDR
It is shown that D. simulans males play an important role in discriminating D. melanogaster females, and the genetics of male discrimination fits well with the inheritance mode of a single locus, dominant for sexual isolation, located in chromosome II near the net mutation. Expand
Abundant genetic variability in Drosophila simulans for hybrid female lethality in interspecific crosses to Drosophila melanogaster.
TLDR
The results suggest that the D. simulans maternal effect hybrid lethality involves a diversity of alleles and/or multiple loci, and is likely to be associated with hybrid sterility or inviability. Expand
The impact of shared ancestral variation on hybrid male lethality – a 16 codon indel in the Drosophila simulans Lhr gene
TLDR
It is shown that the Lhr2 allele lacking the insertion represents an ancestral polymorphism segregating at a moderate frequency in D. melanogaster and D. simulans Lhr alleles. Expand
Drosophila melanogaster and D. simulans rescue strains produce fit offspring, despite divergent centromere-specific histone alleles
TLDR
The data do not dispute the rapid divergence of cid or the coevolution of centromeric components in Drosophila; however, they do suggest that cid underwent adaptive evolution after D. melanogaster and D. simulans diverged and, consequently, is not a speciation gene. Expand
Genetics of hybrid inviability and sterility in Drosophila: The Drosophila melanogaster–Drosophila simulans case
TLDR
The history of genetic analyses of postzygotic isolation in this species pair is reviewed and the genus Drosophila is suitable for such analyses because of its genetic manipulability. Expand
Chromosome reciprocal translocations have accompanied subspecies evolution in bananas
TLDR
Six large reciprocal translocations were precisely characterized and showed that they emerged in different (sub)species of Musa acuminata, the main contributor to currently cultivated bananas, and it was showed that all translocations induced a recombination reduction of variable intensity and extent depending on the translocations.

Cross-species incompatibility between a DNA satellite and a chromatin protein poisons germline genome integrity
TLDR
Experimental evidence that rapid evolution resulted in a cross-species incompatibility between the 359 satellite and Maternal Haploid from Drosophila is offered, suggesting that coevolution between ostensibly inert repetitive DNA and essential chromatin proteins preserves germline genome integrity.

Chromosomes, conflict, and epigenetics: chromosomal speciation revisited.
TLDR
This review will examine both classical and current models of chromosomal speciation and describe the "evolving" theory of genetic conflict, epigenetics, and chromosomal Speciation. Expand

TLDR
Repetitive satellite DNAs within heterochromatin, especially at centromeres, evolve rapidly through molecular drive mechanisms (both meiotic and centromeric), and chromatin-binding proteins must also evolve rapidly to maintain binding capability. Expand
Chromatin Evolution andMolecular Drive in Speciation
Are there biological generalities that underlie hybrid sterility or inviability? Recently, around a dozen “speciation genes” have been identified mainly in Drosophila, and the biological functions ofExpand

A gene that rescues the lethal hybrids between. Drosophila melanogaster and D. simulans.
TLDR
A gene, Lethal hybrid rescue (Lhr 2-95), which rescues the lethal hybrids between Drosophila melanogaster and D. simulans was found on a second chromosome of D. similans from a natural population, and evolutionally implications of Lhr are briefly discussed. Expand
A genetic basis for the inviability of hybrids between sibling species of Drosophila.
TLDR
A mutation of Drosophila melanogaster whose only known effect is the rescue of otherwise lethal interspecific hybrids has been characterized and is interpreted on the basis of a model for the genetic basis of hybrid inviability of complementary genes. Expand
Genetics of hybridization between Drosophila simulans females and D. melanogaster males
TLDR
This work used classical genetic analyses to determine the influence of each major chromosome on the breakdown of sexual isolation between females of D. simulans and D. melanogaster males, suggesting independent evolutionary events during the speciation process in each species. Expand
The unexpected recovery of hybrids in a Drosophila species cross: a genetic analysis.
TLDR
Genetic analysis of the difference between D. simulans strains that produce many versus few hybrid females shows that recovery of hybrid females depends on autosomal, maternally acting gene(s). Expand
Genetic rescue of inviable hybrids between Drosophila melanogaster and its sibling species
TLDR
A single gene difference is discovered that rescues the otherwise inviable male hybrids from the cross between D. melanogaster females and males of its three closest relatives and may shed light on the genetic control of both speciation and development. Expand
Hybrid lethal systems in the Drosophila melanogaster species complex. II. The Zygotic hybrid rescue (Zhr) gene of D. melanogaster.
TLDR
Independence of the hybrid embryonic lethality and the hybrid larval lethality suggested in a companion study was confirmed by employing two rescue genes, Zhr and Hmr (Hybrid male rescue), in doubly lethal hybrids. Expand
Evidence for complex genic interactions between conspecific chromosomes underlying hybrid female sterility in the Drosophila simulans clade.
TLDR
Observations suggest that epistatic interactions between conspecific genes in a hybrid background may be the prevalent mode of hybrid sterility between recently diverged species. Expand
Hybrid lethal systems in the Drosophila melanogaster species complex. I. The maternal hybrid rescue (mhr) gene of Drosophila simulans.
TLDR
Another rescue gene located on the second chromosome of simulans, mhr (maternal hybrid rescue) that, when present in the mother, rescues CsXmXs females from embryonic lethality is reported. Expand
Genetic studies on premating isolation in Drosophila simulans. I.AD. simulans line highly crossable with D. melanogaster.
TLDR
The S2 line of Drosophila simulans, an isofemale line from a natural population at Mishima, Japan, was found to have high crossability with D. melanogaster, caused by at least two genes which act additively. Expand
Further studies on the lethal hybrid rescue(LHR) gene of Drosophila simulans.
TLDR
Further characterization of Lhr gene, which rescues the lethal hybrid of D. melanogaster and D. simulans, was made using several mutants of D.'s simulans to discuss the character of hybrid lethality between the two species. Expand
