The paper shows that the teleost gonad originates from three embryonic tissues, challenging the idea that pronephric contribution is an amniote innovation.

The paper identifies a recessive oca2 mutation causing albinism in Xiphophorus hellerii fish and explores its role in pigment biology and melanoma.

The paper shows that hexaploid Carassius gibelio females use achiasmatic meiosis to produce clonal eggs, while males have reduced fertility due to meiotic issues, and B chromosomes are stably inherited as univalents.

This study identifies a retrovirus insertion near the alkal2a gene as the genetic basis for a novel iridescent color trait in swordtail fish, showing its role in chromatin changes and predator interaction signals.

The paper investigates how hybridization affects gene expression in brain tissues by identifying cell type-specific regulatory variation in interspecies fish hybrids.

The paper compares single-cell profiles of Xiphophorus melanomas to human melanomas, showing that Xiphophorus melanomas mimic human melanoma cellular heterogeneity.

The paper tests the function of adgre5 alleles in melanoma development using Xiphophorus hybrids and finds that the X. birchmanni allele suppresses melanoma while the X. malinche allele does not.

The paper identifies a genetic basis for a sexual mimicry polymorphism in swordtail fish and links it to behavioral interactions that may maintain the polymorphism.

The paper identifies a locus in one Xiphophorus species that represses an oncogene from another species, providing insights into hybrid incompatibility and pigment cell regulation.

The paper shows that local ancestry in hybrid swordtail fish populations is repeatable due to strong early selection, and this repeatability increases with deeper evolutionary divergence.

The paper identifies a candidate sex determination locus in the European green toad, involving structural variation in the bod1l gene and a Y-specific non-coding RNA.

The paper provides complete genomes for all 26 Xiphophorus species, resolves conflicting phylogeny, and shows hybridization precedes speciation in this genus.

The paper compares transcriptional profiles of two tumor types in a transgenic medaka model to identify how transcriptomic backgrounds influence oncogenic outcomes.

The study identifies a non-functional sdY gene variant in XY Chinook salmon females that disrupts testicular differentiation by impairing estrogen synthesis.

This paper reviews and reanalyzes data on the evolution of sex chromosomes in guppies and their relatives, finding no nonrecombining sex determining region or evolutionary strata in P. reticulata.

RADSex is a computational workflow for analyzing RAD-Seq data to identify sex determination systems, uncovering new sex-specific markers in fish species.

This study characterizes the sex determination system and sex chromosomes in goldfish, identifying a large non-recombining region on linkage group 22 as the likely Y chromosome and developing sex-linked genetic markers.

The paper presents a high-quality draft genome assembly of Oryzias javanicus, focusing on its adaptation to salinity.

The paper presents a chromosome-scale genome assembly of yellow perch and identifies a Y-specific duplication of the amhr2 gene as a candidate sex determination gene.
