Data from: Predation-associated differences in sex-linkage of wild guppy coloration
Evolutionary theory predicts that the sex-linkage of sexually selected traits can influence the direction and rate of evolutionary change, and also itself be subject to selection. Theory abounds on how sex-specific selection, mate choice, or other phenomena should favor different types of sex-linked inheritance, yet evidence in nature remains limited. Here we use hormone assays in Trinidadian guppies to explore the extent to which linkage of male coloration differs among populations adapted to varying predation regimes. Results show there is consistently higher degree of X- and autosomal linkage in body coloration among populations adapted to low-predation environments. More strikingly, analyses of an introduced population of guppies from a high to a low predation environment suggest that this difference can change in 50 years or less.

Data from: Snakeskin gourami (Trichopodus pectoralis) exhibits XX/XY sex determination and putative young Y chromosome shares sex chromosomal linkage homologies with those of amniotes
<p class="CxSpFirst"><span>Snakeskin gourami (<i>Trichopodus pectoralis</i>) is one of the most common air-breathing freshwater fish of the Indochina peninsula. It has a high meat yield and is one of the top five aquaculture freshwater fish in Thailand. However, it takes 2–3<b> </b>years for adults to reach sexual maturity. Snakeskin gourami is not externally sexually dimorphic and its sex determination remains unknown, complicating many aspects of broodstock management including sex manipulation. Understanding the sex determination system will contribute significantly towards full-scale commercialization. By characterizing the sex determination system in snakeskin gourami using cytogenetic approaches and Diversity Arrays Technology, we identified sex-specific loci in 16 phenotypic sex assignments of snakeskin gourami. Of the 39 loci present in all males, 4<b> </b>male-linked loci reached the criteria of moderately sex-linked loci (70:30; males:females and 80:20; males:females). By contrast, only one female-linked locus was detected from moderately sex-linked loci. This suggests that snakeskin gourami exhibits an XX/XY sex determination mode. No different chromosomal patterns were observed in karyotype, C-banding, and microsatellite repeat fluorescence <i>in situ</i> hybridization mapping between males and females, and no male-specific loci of 100:0 (males:females) were observed in snakeskin gourami. This suggests that the putative Y chromosome is young and the non-recombination region is very cryptic. A total of<b> </b>10.26% male-linked loci were involved with the sex developmental pathway in vertebrates and 5.13% showed partial homology with several amniote sex chromosomal linkages. Surprisingly, the hypothesis of an ancestral amniote super-sex chromosome with overlaps of partial sex chromosomal linkages was also found in teleosts. This approach provides a solid baseline to reveal the sex determination mechanism<b> </b>and identify potential sex determination regions in teleosts, allowing further investigation of genetic improvements in snakeskin gourami.</span></p>
