Data from: A phylogeographic investigation of the hybrid origin of a species of swordtail fish from Mexico
- 负责人：
- DOI：
- doi:10.5061/dryad.524t4v16
- 摘要：
- t do not involve polyploidization as a mechanism. The swordtail fish, Xiphophorus clemenciae, shows common hall-marks of a hybrid origin and still overlaps
Data from: Long-term experimental hybridisation results in a heterologous transition and the evolution of a new sex chromosome in swordtail fish
- 负责人：

- doi:10.5061/dryad.7h54h66
- 摘要：
- or transitions. However, the evolutionary causes and genomic mechanisms underlying this variation and instability are yet to be understood. Here we report
Data from: Multiple mating and reproductive skew in parental and introgressed females of the live-bearing fish Xiphophorus birchmanni
- 负责人：
- DOI：
- doi:10.5061/dryad.878p7
- 摘要：
- . In this study, we characterized patterns of multiple mating and reproductive skew in a naturally hybridizing swordtail fish species, Xiphophorus birchmanni
Data from: Repeated losses of PRDM9-directed recombination despite the conservation of PRDM9 across vertebrates
- 负责人：
- DOI：
- doi:10.5061/dryad.gf7r3
- 摘要：
- of its predicted binding affinity, suggesting that all domains are necessary for directing recombination. Indeed, as we show, swordtail fish carrying only a partial
Data from: Ontogeny and phylogeny in the northern swordtail clade of Xiphophorus
- 负责人：
- DOI：
- doi:10.5061/dryad.502
- 摘要：
- how developmental patterns have changed phylogenetically in the northern swordtail clade of Xiphophorus. We reared individuals of an outgroup and seven of nine species
Data from: Ancient hybridization and genomic stabilization in a swordtail fish
- 负责人：
- DOI：
- doi:10.5061/dryad.tm47d
- 摘要：
- results suggest that selection has played a role in removing hybrid ancestry from certain functionally important regions. Combined with findings
Data from: High-resolution mapping reveals hundreds of genetic incompatibilities in hybridizing fish species
- 负责人：
- DOI：
- doi:10.5061/dryad.q6qn0
- 摘要：
- for linkage disequilibrium between unlinked genomic regions in naturally occurring hybrid populations of swordtail fish. We estimate that hundreds of pairs of genomic region
Data from: The evolutionary history of Xiphophorus fish and their sexually selected sword: a genome-wide approach using restriction site-asso

- DOI：
- doi:10.5061/dryad.728b4
- 摘要：
- -associated DNA (RAD) (?66000 SNPs) to estimate the phylogenetic relationships among all 26 species of swordtail and platyfish (genus Xiphophorus) from
Data from: Maternal size and age shape offspring size in a live-bearing fish, Xiphophorus birchmanni

- DOI：
- doi:10.5061/dryad.rp131
- 摘要：
- in maternal environments. To clarify this pattern, we asked how maternal size, age and condition are related to each other in several populations of the swordtail
Data from: High opportunity for postcopulatory sexual selection under field conditions
- 负责人：
- DOI：
- doi:10.5061/dryad.9jd86
- 摘要：
- . Here, we use extensive behavioral observations of a semi-natural population of Hawaiian swordtail crickets, Laupala cerasina, and molecular paternity
