- Title
Fish Cytogenetics: Present and Future.
- Authors
Rossi, Anna Rita
- Abstract
Fish is the most species-rich class of vertebrates, including a number of species that correspond to about half of the total vertebrates [[1]]. A high number of variable transposable elements (TEs) is also present within the most compact fish genomes that include a small fraction of repetitive sequences: indeed TEs seem to have a rapid turnover in teleost fish genomes [[16]]. The sequencing of the first fish genome (and second vertebrate, after human) dates back to about twenty years ago [[13]]: the teleost I Takifugu rubripes i , commonly known as the Japanese pufferfish, was chosen as the target species, because of its compact genome (0.39 Gb), one of the smallest in size within vertebrates. The large differences in fish genome sizes are associated with the variable amount of repetitive genetic elements [[15]]: their contribution to the total genome is higher than in mammals, and these sequences play a role in divergence and rapid evolution of sex-determining loci [[16], [18]].
