Genome duplication, a trait shared by 22000 species of ray-finned fish.
The phylogeny and synteny data suggest that the common ancestor of zebrafish and pufferfish, a fish that gave rise to approximately 22000 species, experienced a large-scale gene or complete genome duplication event and that the puffer fish has lost many duplicates that the zebra fish has retained.

The African coelacanth genome provides insights into tetrapod evolution.
Through a phylogenomic analysis, it is concluded that the lungfish, and not the coelacanth, is the closest living relative of tetrapods. Expand
The spotted gar genome illuminates vertebrate evolution and facilitates human-to-teleost comparisons
To connect human biology to fish biomedical models, we sequenced the genome of spotted gar (Lepisosteus oculatus), whose lineage diverged from teleosts before teleost genome duplication (TGD). TheExpand
Comparative genomics provides evidence for an ancient genome duplication event in fish.
It is estimated that the unlinked duplicated zebrafish genes are between 300 and 450 Myr, which means that genome duplication could have provided the genetic raw material for teleost radiation and the loss of different duplicates in different populations may have promoted speciation in ancient teleost populations.

Evolution of pigment synthesis pathways by gene and genome duplication in fish
The results support an important role of the FSGD and other types of duplication in the evolution of pigmentation in fish, and suggest teleost fishes apparently have a greater repertoire of pigment synthesis genes than any other vertebrate group. Expand
The genome of the platyfish, Xiphophorus maculatus, provides insights into evolutionary adaptation and several complex traits
It is found that genes implicated in cognition show an unexpectedly high rate of duplicate gene retention after the teleost genome duplication event, suggesting a hypothesis for the evolution of the behavioral complexity in fish, which exceeds that found in amphibians and reptiles. Expand
Gene evolution and gene expression after whole genome duplication in fish: the PhyloFish database
The PhyloFish database is developed to provide de novo assembled gene repertoires in 23 different ray-finned fish species including two holosteans and 21 teleosts and to obtain the most exhaustive gene repertoire possible in each species that allows between-species comparisons to study the evolution of gene expression in different lineages.

Multiple Sex-Associated Regions and a Putative Sex Chromosome in Zebrafish Revealed by RAD Mapping and Population Genomics
The data show thatsex determination in zebrafish is polygenic and that different genes may influence sex determination in different strains or thatDifferent genes become more important under different environmental conditions. Expand
Adaptive sequence evolution in a color gene involved in the formation of the characteristic egg-dummies of male haplochromine cichlid fishes
Modifications of existing signal transduction mechanisms might have evolved in the haplochromine lineage in association with the origination of anal fin egg-dummies, highlighting the importance of further investigations of the comparative genomic basis of the phenotypic diversification of cichlid fishes.

Pigmentation Pathway Evolution after Whole-Genome Duplication in Fish
The hypothesis that WGDs have promoted the increase of complexity and diversity during vertebrate phenotypic evolution is strongly supported. Expand
