Speciation—the splitting of one species into two—occurs by the evolution of any of several forms of reproductive isolation between taxa, including the intrinsic sterility and inviability of hybrids. Abundant evidence shows that these hybrid fitness problems are caused by incompatible interactions between loci: new alleles that become established in one species are sometimes functionally incompatible with alleles at interacting loci from another species. However, almost nothing is known about… Expand
Hybrid Incompatibility in Drosophila : An Updated Genetic and Evolutionary Analysis
Negative interactions between independently evolved genes in two species are responsible of incompatibility of their hybrid, manifested by sterility and inviability. The heterogametic sex (XY malesExpand
A Single Gene Causes Both Male Sterility and Segregation Distortion in Drosophila Hybrids
TLDR
It is shown that the same gene, Overdrive, causes both male sterility and segregation distortion in F1 hybrids between the Bogota and U.S. subspecies of Drosophila pseudoobscura, suggesting that genetic conflict may be an important evolutionary force in speciation. Expand
Genetics and Lineage-Specific Evolution of a Lethal Hybrid Incompatibility Between Drosophila mauritiana and Its Sibling Species
TLDR
The genetics and evolutionary history of a lethal hybrid incompatibility between Drosophila mauritiana and its two sibling species, D. sechellia and D. simulans, are characterized and it is inferred that hlx-Su(hlx) hybrid lethality is likely caused by a derived-ancestral incompatibility, a hypothesis that can be tested directly when the genes are identified. Expand
Functional Divergence Caused by Ancient Positive Selection of a Drosophila Hybrid Incompatibility Locus
TLDR
It is demonstrated that transgenic copies of the X-linked Hybrid male rescue (Hmr) gene have functionally diverged to cause F1 hybrid incompatibility between D. simulans and D. mauritiana, and it is suggested that multiple substitutions driven by natural selection may be a general phenomenon required to generate hybrid incomp compatibility alleles.

Evolution and genetics of hybrid lethality in mimulus
TLDR
This work addresses long-standing questions regarding the origin of reproductive barriers and the mechanisms that allow them to persist in systems where gene flow is ongoing, by studying the evolutionary genetics of hybrid lethality that occurs between two closely related species of yellow monkeyflower, Mimulus guttatus and M. nasutus. Expand
Evolution of the Drosophila Nuclear Pore Complex Results in Multiple Hybrid Incompatibilities
TLDR
The protein encoded by Nup160 directly interacts with that of another hybrid lethality gene, Nup96, indicating that at least two lethal hybrid incompatibility genes have evolved as byproducts of divergent coevolution among interacting components of the Drosophila nuclear pore complex. Expand
Genetic Analysis of Hybrid Incompatibilities in Drosophila
TLDR
Fine-scale genetic analyses and molecular analyses show that the X-chromosome plays a special role in the evolution of hybrid sterility, and that the genes causing hybrids sterility and inviability usually diverge between species by positive natural selection. Expand
Incompatibility of Nuclear and Mitochondrial Genomes Causes Hybrid Sterility between Two Yeast Species
TLDR
It is speculated that AEP2 and OLI1 have evolved during the adaptation of S. bayanus to nonfermentable carbon sources, thereby driving speciation. Expand
Evidence of Natural Selection Acting on a Polymorphic Hybrid Incompatibility Locus in Mimulus
TLDR
It is shown that a 320-kb region containing the hms1 incompatibility allele has risen to intermediate frequency in this population by strong natural selection, providing direct evidence that natural selection within plant species can lead to hybrid dysfunction between species. Expand
EPISTASIS MODIFIES THE DOMINANCE OF LOCI CAUSING HYBRID MALE STERILITY IN THE DROSOPHILA PSEUDOOBSCURA SPECIES GROUP
TLDR
It is shown that epistasis elevates the apparent dominance of individually recessive‐acting QTL such that they can contribute to F1 hybrid sterility, which may offer a possible explanation for why identification of dominant‐acting autosomal “speciation genes” has been challenging. Expand

TLDR
Although molecular genetic data are limited, early findings suggest that “speciation genes” correspond to loci having normal functions within species and that these loci sometimes diverge as a consequence of evolution in gene regulation. Expand
Genetic analysis of speciation by means of introgression into Drosophila melanogaster.
TLDR
It is shown that this hybridization can permit systematic and precise delineation of the genetic and molecular basis of speciation, and the extent of interspecific genetic divergence underlying hybrid male sterility is far greater than expected. Expand
A rapidly evolving MYB-related protein causes species isolation in Drosophila
TLDR
The cloning of the first, to the authors' knowledge, Drosophila melanogaster gene involved in hybrid incompatibilities, Hybrid male rescue (Hmr) is reported, finding that Hmr encodes a protein with homology to a family of MYB-related DNA-binding transcriptional regulators. Expand
A fine-scale genetic analysis of hybrid incompatibilities in Drosophila.
TLDR
A fine-resolution genetic screen is presented that allows systematic counting, mapping, and characterizing of a large number of hybrid incompatibility loci in a model genetic system and confirms the epistatic nature of hybrid lethality by showing that all of the incompatibilities are rescued when the D. melanogaster X is replaced with a D. simulans X.

It is suggested that duplicate genes, and more generally any kind of genomic redundancies, provide a powerful substrate for the origin of genomic incompatibilities in isolated populations. Expand

Adaptive protein evolution at the Adh locus in Drosophila
TLDR
A simple statistical test of the neutral protein evolution hypothesis is proposed based on a comparison of the number of amino-acid replacement substitutions to synonymous substitutions in the coding region of a locus, finding that there are more fixed replacement differences between species than expected.

Polymorphism levels are consistent with a ranking of effective population sizes, from low to high, in the following order: D. sechellia, D. melanogaster,D.mauritiana, and D. simulans. Expand

TLDR
Overall, D. melanogaster autosomes harbor an excess of amino acid replacement polymorphisms relative to D. simulans, and range expansion from Africa appears to have had little effect on synonymous-to-replacement polymorphism ratios. Expand
Dominance, epistasis and the genetics of postzygotic isolation.
TLDR
A model of two-locus incompatibilities is presented that distinguishes among three types of hybrid interactions: those between heterozygous loci (H(0), those between aheterozygous and a homozygous (or hemizygous) locus (H (1), and those between homozygou loci(H(2)); the relative fitnesses of hybrid genotypes are predicted by calculating the expected numbers of each type of incompatibility.
