In two papers published at about the same time almost thirty years ago, Frank (Evolution, 45, 1991a, 262) and Hurst and Pomiankowski (Genetics, 128, 1991, 841) independently suggested that divergence of meiotic drive systems—comprising genes that cheat meiosis and genes that suppress this cheating—might provide a general explanation for Haldane's rule and the large X‐effect in interspecific hybrids. Although at the time, the idea was met with skepticism and a conspicuous absence of empirical… 
Chromosomal evolution in Raphicerus antelope suggests divergent X chromosomes may drive speciation through females, rather than males, contrary to Haldane's rule
TLDR
A novel hypothesis is argued that postulates that the expansion of heterochromatic blocks in the homogametic sex can contribute to post-zygotic isolation, i.e., female hybrid incompatibility, the converse of Haldane’s rule.
Evaluating genomic signatures of “the large X‐effect” during complex speciation
TLDR
Evidence for greater differentiation on the X (or Z) vs. the autosomes is summarized and theory for why large X‐effects exist for hybrid incompatibilities and, more generally, for loci mediating local adaptation is reviewed.
Strong hybrid male incompatibilities impede the spread of a selfish chromosome between populations of a fly
TLDR
It is shown that SRs has remained at a constant frequency in North Africa, and failed to spread in Spain, and the source of the stepped frequency variation is genetic incompatibility between the SRs chromosome and the genetic backgrounds of the adjacent population, preventing SRs spreading northward.
Sexual antagonism leads to a mosaic of X–autosome conflict
TLDR
The X likely contains a mosaic pattern of loci that conflict with autosomes over sexually antagonistic traits, and the overall tendency for a female or male bias on the X depends on prior assumptions about the distribution of key parameters across X-linked loci.

The X chromosome favors males under sexually antagonistic selection

TLDR
A simple mathematical model is presented and it is found that the exact opposite bias exists; the X chromosome is revealed to be a welcome spot for mutations that benefit males at the expense of females.
Selfish genetic elements
TLDR
Though long dismissed as genetic curiosities, with little relevance for evolution, they are now recognized to affect a wide swath of biological processes, ranging from genome size and architecture to speciation.
Faster-haplodiploid evolution under divergence-with-gene-flow: simulations and empirical data from pine-feeding hymenopterans
TLDR
It is hypothesize that haplodiploid and diploid populations evolving according to the estimated divergence history of N. lecontei and N. pinetum undergo divergence-with-gene-flow and sympatric speciation more readily than diploids.

Hybrid sterility genes in mice (Mus musculus): a peculiar case of PRDM9 incompatibility.
TLDR
Prdm9-dependent hybrid sterility points to incompatibilities affecting meiotic recombination as a possible mechanism of reproductive isolation between (sub)species.

FURTHER EVIDENCE AGAINST MEIOTIC‐DRIVE MODELS OF HYBRID STERILITY
  • J. Coyne, H. A. Orr
  • Biology, Medicine
    Evolution; international journal of organic evolution
  • 1993
TLDR
A direct experimental test of the meiotic-drive explanation for Haldane's rule is provided, which explains only hybrid sterility and not inviability, and mutations causing preferential segregation of a chromosome may arise frequently, but are more likely to increase in frequency when on sex chromosomes than on autosomes.
Meiotic drive and unisexual hybrid sterility: a comment.
TLDR
Their model has considerable difficulty in explaining cases of hybrid inviability as a result of meiotic drive, except by invoking ad hoc assumptions about the involvement of transposable elements in the causation of meiosis drive, which lack empirical support.
The role of meiotic drive in hybrid male sterility
  • S. R. McDermott, M. Noor
  • Biology, Medicine
    Philosophical Transactions of the Royal Society B: Biological Sciences
  • 2010
TLDR
The recent empirical evidence for a link between drive and hybrid male sterility is discussed, suggesting a possible mechanistic explanation for this link in the context of chromatin remodelling and the population genetics of drive that allow it to contribute to speciation are revisit.
DIVERGENCE OF MEIOTIC DRIVE‐SUPPRESSION SYSTEMS AS AN EXPLANATION FOR SEX‐BIASED HYBRID STERILITY AND INVIABILITY
  • S. Frank
  • Biology, Medicine
    Evolution; international journal of organic evolution
  • 1991
TLDR
It is shown that divergence of meiotic drive systems can explain the two generalizations about speciation even if large departures from Mendelian segregation are rarely observed.
Rapid rise and fall of selfish sex-ratio X chromosomes in Drosophila simulans: spatiotemporal analysis of phenotypic and molecular data.
TLDR
The data suggest that X(SR) chromosomes started declining first on the African continent, then in Mayotte, and finally in Madagascar and strongly support a scenario of rapid cycling of X chromosomes.
Heterochromatin and genetic conflict
  • C. D. Meiklejohn
  • Biology, Medicine
    Proceedings of the National Academy of Sciences
  • 2016
TLDR
A recent study in PNAS has identified a gene required for sex-ratio distortion in Drosophila simulans, providing novel insight into the genetic and molecular mechanisms used by these selfish elements and their effects on genome evolution and species formation.
Rapid evolution of a Y-chromosome heterochromatin protein underlies sex chromosome meiotic drive
TLDR
It is shown that a young and rapidly evolving X-linked heterochromatin protein 1 (HP1) gene, HP1D2, plays a key role in the classical Paris sex-ratio (SR) meiotic drive occurring in Drosophila simulans, providing evidence that the rapid evolution of genes controlling the heterochromeatin structure can be a significant source of intragenomic conflicts.
GENOMIC CONFLICTS UNDERLYING HALDANE'S RULE
TLDR
Find strong theoretical and empirical support for the hypothesis that hybrid disruption could result from selfish genetic elements attempting to pervert the sex ratio and remain confident that the evolution of sex ratio distorters within species, and selfish Genetic elements in general, can in principle explain cases of hybrid sterility.
Recurrent Selection on the Winters sex-ratio Genes in Drosophila simulans
Selfish genes, such as meiotic drive elements, propagate themselves through a population without increasing the fitness of host organisms. X-linked (or Y-linked) meiotic drive elements reduce the
Genome rearrangements and pervasive meiotic drive cause hybrid infertility in fission yeast
TLDR
It is found that chromosomal rearrangements and related recombination defects are major but not sole causes of hybrid infertility of two recently diverged fission yeast species Schizosaccharomyces pombe and S. kambucha.
