“…This difference may be due to an X-linked paracentric inversion that is large enough to contain all four microsatellites and renders recombinant haplotypes inviable in male eggs. Chromosomal inversions are associated with meiotic drive in several other cases of SR in Diptera (Jaenike 2001). Comparison of two-locus autosomal haplotypes in F2 flies indicates that recombination does not occur in males (G. S. Wilkinson, unpublished data), as is true for other Diptera (Lenormand 2003).…”

Genetic linkage between a sexually selected trait and X chromosome meiotic drive

Previous studies on the stalk-eyed fly, Cyrtodiopsis dalmanni, have shown that males with long eye-stalks win contests and are preferred by females, and artificial selection on male relative eye span alters brood sexratios. Subsequent theory proposes that X-linked meiotic drive can catalyse the evolution of mate preferences when drive is linked to ornament genes. Here we test this prediction by mapping meiotic drive and quantitative trait loci (QTL) for eye span. To map QTL we genotyped 24 microsatellite loci using 1228 F2 flies from two crosses between lines selected for long or short eye span. The crosses differed by presence or absence of a drive X chromosome, X D , in the parental male. Linkage analysis reveals that X D dramatically reduces recombination between X and X D chromosomes. In the X D cross, half of the F2 males carried the drive haplotype, produced partially elongated spermatids and female-biased broods, and had shorter eye span. The largest QTL mapped 1.3 cM from drive on the X chromosome and explained 36% of the variation in male eye span while another QTL mapped to an autosomal region that suppresses drive. These results indicate that selfish genetic elements that distort the sex-ratio can influence the evolution of exaggerated traits.

“…Although heteromorphic sex chromosomes also occur in groups with high numbers of monobrachial chromosomes, such as Perciformes (e.g., Ueno and Takai 2008), their presence is strongly correlated with those groups with a propensity for the fixation of bi-brachial elements, such as in Characiformes and Siluriformes, suggesting that meiotic drive could have aided the establishment of newly arisen sex chromosome systems. Given that the drive mechanism helps establish a new sex system, it is likely counterbalanced by drive suppressors; otherwise the species could become extinct (Jaenike 2001).…”

Mechanisms of accumulation based on typical centromeric drive or of chromosomes carrying pericentric inversions are adjusted to the general karyotype differentiation in the principal Actinopterygii orders. Here, we show that meiotic drive in fish is also supported by preferential establishment of sex chromosome systems and B chromosomes in orders with predominantly bi-brachial chromosomes. The mosaic of trends acting at an infra-familiar level in fish could be explained as the interaction of the directional process of meiotic drive as background, modulated on a smaller scale by adaptive factors or specific karyotypic properties of each group, as proposed for the orthoselection model.

“…Selfish meiotic-drive alleles may distort the sex ratio to their own advantage leading to their increase in frequency in the population, which in turn causes selection for genes that suppress drivers and restore the sex ratio (Pomiankowski and Hurst, 1993). Such sex ratio distorters are typically found on the X chromosome (Hurst and Pomiankowski, 1991;Jaenike, 2001). When two diverged populations hybridize, the drivers may escape the control of the suppressors and cause male sterility.…”

Speciation through evolution of sex-linked genes

Identification of genes involved in reproductive isolation opens novel ways to investigate links between stages of the speciation process. Are the genes coding for ecological adaptations and sexual isolation the same that eventually lead to hybrid sterility and inviability? We review the role of sex-linked genes at different stages of speciation based on four main differences between sex chromosomes and autosomes; (1) relative speed of evolution, (2) non-random accumulation of genes, (3) exposure of incompatible recessive genes in hybrids and (4) recombination rate. At early stages of population divergence ecological differences appear mainly determined by autosomal genes, but fastevolving sex-linked genes are likely to play an important role for the evolution of sexual isolation by coding for traits with sex-specific fitness effects (for example, primary and secondary sexual traits). Empirical evidence supports this expectation but mainly in female-heterogametic taxa. By contrast, there is clear evidence for both strong X-and Z-linkage of hybrid sterility and inviability at later stages of speciation. Hence genes coding for sexual isolation traits are more likely to eventually cause hybrid sterility when they are sex-linked. We conclude that the link between sexual isolation and evolution of hybrid sterility is more intuitive in male-heterogametic taxa because recessive sexually antagonistic genes are expected to quickly accumulate on the X-chromosome. However, the broader range of sexual traits that are expected to accumulate on the Z-chromosome may facilitate adaptive speciation in female-heterogametic species by allowing male signals and female preferences to remain in linkage disequilibrium despite periods of gene flow.
